We live in a mid terrace and the walls appear to be very thin. Often can hear neighbour shouting at their daughter, can sometimes hear the radio/tv etc. But the most annoying thing of all is their squeaky door!!!!!!! At all hours of the day and night i can hear my neighbours opening and closing a door upstairs that is incredibly creaky!!! Its so loud it sounds like its in our house. When we moved in i even had to double check it wasnt one of our doors. Its driving me crazy - would i be unreasonable to go and introduce myself to them and give them some WD40 to sort it out? We didnt move in long ago and havent met them yet either!
