When I left school at 15, my parents told me I had to start paying board, $50 a week, they still fed me, but I bought all my own toiletries, clothes, etc.

then when my BF moved in when I was 18, he also paid $50 a week and we contributed 3 monthly to the electricity bills, phone bills etc.

TBH I never begrudged my parents this, but that being said, my brother moved back in with his GF in while they were building their second home, my parents never asked them for a cent! was not happy about that!

Also I still have 2 brothers living at my parents house, (25, 23) one of whom has no job and never pays a cent either, its really not fair, but trying to get money out of him is like trying to get blood from a stone.

In my situation I think it was totally fair, seeing as I left school, got a job, (against their wishes) If I had stayed at school, I doubt they would have asked me for money, unless it was to contribute towards a high bill.

I dont see a problem with expecting family members who are working to contribute in some way towards the running of a household that they live in, as previous posters have mentioned, it does set you up to learn how to survive in the "real world".
