New neighbours moved in about 7 months ago, ever since then we have the routine - we take the bins out and they bring the bins in.
It was never spoken about but it's what we did with previous owners and seemed to be working fine past 7 months. However, past two weeks, although we have taken the bins out, my neighbours have only taken their own bins in.
AIBU to approach them asking if everything is okay? Or should I just stop taking their bins out? Why would they suddenly stop, pretty rude to be honest.
