I think your mate needs to give him a good slap.On serious note, I lived with a woman with two late teen children, the lad was fine but her daughter would try to push the boundries daily, on one ocasion my ex had gone to visit her other daughter, we'd all sat down and discussed whom was to do what chores to try to live in some form of harmony while the ex was away. I took the cooking duties, the lad general cleaning, daughter the washing up. First night I cooked spag bol, son tidied up, daughter refused to wash. Next morning she sat taunting me, stating she didn't have to do anything and that as far as she was concerned the pots could stay there all week. At this point I emptied the large saucepan, that I'd cooked the dinner in, straight over her head, it wasn't a pretty sight with cold spagetti, sauce and the odd bit of mince spread pretty evenly all over her, but she got the message.Never seen anyone quite so keen on washing up after that.There has to be rules and your friend must have the right to enforce them
3 way conversation - 3 different viewpointsYour mate - I've been living with this woman for 9 months, everything is fine, why does her son come home and spoil it?Son - I blame my parents for breaking up, who is this man who lives in my mum's house telling me what to do?Mum - I feel guilty about everything.......Talk, talk, talk. Compromise, compromise, compromise
If I can offer some hope it's the fact that there's a huge difference between freshers and final year students, majority of kids after the full University experience mature into well rounded adults. If only your M8 can hang in there.
