That house was pretty unique, actually. A holdover from the "black country" days of coal mining and heavy industry. For its' time, it was considered one of the more posh houses in the neighborhood, fit for a foreman or higher-level manager as opposed to a worker.
Today, the house exists at the joining edge of two separate neighborhoods, each of which sits in two different counties, though this is really not directly relevant per se. But what is relevant is that the house does not sit on any street, but at the end of a series of alleyways and maze-like cut-throughs between these older workers cottages and muse houses. Actually, it sits at the end of
two series of alleyways and maze-like cut-throughs, each alley leading to the house zigzagging through its respective neighborhood/county on either side of the house.
Because of this unique situation, the house eventually accumulated a steady traffic of people using it as a cut-through to get from one neighborhood to the other, as any other route required a drive of several miles.
This may sound improbable, and like the house had become some kind of public property, but this was not the case. Actually, it's easy to imagine the actual situation: Friends of the couple that lived in the house would sometimes drop by through one door for afternoon tea, and then when finished leave through the other door, to go grocerie shopping or visiting relatives in the other neighborhood.
The utility of the house as cut-through was well-known, of course, so that when it became known that actual friends of the couple were going to visit/cut through, they would sometimes accumulate friends and acquantances who would want to come along so as to partake of the convenience of cutting through.
These secondary friends and acquantences would of course eventually come by themselves and sometimes not even stay for tea: They merely would like to know if it was OK if they could pass through and, no bother, not importune them for tea or biscuits. As the secondary friends became regulars, they'd of course bring along tertiary friends until after a while there was a steady traffic of strangers passing through the kitchen and front parlour of the house.
The husband, actually the son of a lifelong miner, was the manager of a dairy distributor, got tired of this and decided one day to brick up the bottom level, so that from the front parlour it was only possible to get to the kitchen by traveling up the stairs to the first floor and then walking down the back stairs down to ground.
For a while they had some piece as it became quite clear what the motivation was. Some of the actual friends understood, but others in the area considered it rude and there were Chinese whispers around the neighborhood suggesting that the real cause was some sort of marital difficulties.
Eventually, however, the primary friends started moving up the stairs to get over to other side of the house and out the door to access the other neighborhood, and soon followed secondary friends and, eventually, strangers. It got so bad that they had to socialize appropriate times for the cross over. The husband felt like that boatman mentioned in the Greek myths that ferried people from life to the full-fledged afterlife, but he couldn't remember the name of that chap.
Eventually, however, he made the decision to brick up the second floor as well, and this caused some issues: The wife's job occurred in a county beyond one of the adjoining neighborhoods while the husband's job was local to the other adjoining neighborhood. As a result, it often made sense for them to sleep in separate halves of the house.
They did, however, develop a system for passing small objects to each other through the windows by placing the objects in small baskets at the end of poles. They had wall-knocks to signal or, if one of them was not within hearing distance of a knock, they'd phone and ring three times before hanging up to signal the need to "talk" through the knocks.
After months turned into years, they eventually forgot what each other looked like. You may think that's absurd, but how many married couples look at old photos of each other? They just assumed they did still know what each other looked like but in reality they had forgotten. That's why, at an antique show + auction one Spring afternoon, they bid against each other for the same item, a small inlaid snuff box from the 1880s.
Between the two of them, bidding soared into the high 3 digits for the snuff box, with other bidders rapidly falling away. As they bid each of them felt a certain animosity towards the other, for muscling in on a special item that only he or she had the proper eye to appreciate. As a result, bidding rose well beyond what the item was worth, and even well beyond what either of them would have otherwise paid for it, no matter how charming. More to the point, the bidding surpassed even what money they had in their account (which was a joint account after all) and even beyond the conservative credit line given to them by the bank. In other words, neither of them could afford it. And because this antique show was a small, local affair, there had been no credit checks so both of them had to forfeit the item. It was offered to the third-placed bidder for £125.
