Next doors payslip (well actually it was a P60) came through my door. I opened it not having read the address as looked exactly like mine and had to pause because the total was far more than I got paid then I realised as looks exactly what work sent to me. Now I'm embarrassed and don't know what to do. I've opened it but do you think my neighbour will believe this? We wave and say hi etc but don't really know each other that well.
WWYD???
