My previous neighbour was an elderly gentleman and he had to sell his house to go into a home.
I would put his bin out for him as our path is steep and he struggled to get the bin up it.
When he moved out and the house was on the market I used his bin and put it out with mine.
When the house was bought by a young couple it needed a lot of work doing, this work has been ongoing now for several months and throughout I have continued to put the bin out, they haven't been living on the house so various tradesmen and decorators have been using the bin and I have put it out for them in their absence.
Well they have finally moved in (I think though they may just be staying over some times?)
Last night I forgot to put the bin out so dashed out this morning in my dressing gown and wellies. Well next door have put their own bin out and just left mine. AIBU to be slightly peeved that they didn't bother putting mine out despite knowing I have done theirs for months.
Yes I know it's a minor irritation in the grand scheme of things.
