I definitely am BU 
because it’s none of my bloody business. But I thought i’d put it out to MN speculation and see what you lot can come up with.
Neighbour comes home from work at random times in the day, goes into the house for less than a minute. Sometimes only about 20 seconds and then leaves again. I don’t even think its long enough to use the toilet most times. TBH I doubt I would notice except his job is in a care role and he drives a minibus whilst working so I hear the thing when it comes in. He always has at least one of the people he cares for in the bus when he comes home so is clearly on the clock. He sometimes brings the person into the house with him but more often just leaves them on the bus. He sometimes has a colleague with him too so people at work know he is doing this. I live in a small town where everyone knows what you had for breakfast and there were rumours that this man’s wife had cheated on him a few years ago. I have no idea if that is true but I wondered if he was coming home during the day to check up on her. However he does it even when she is working so not at home.
So, what do you reckon? Other than me needing a hobby.
