My 16 year old DS is doing an apprenticeship and is on more than the minimum rate for an apprentice his age. His take home pay monthly is £750 a month. He pays his own phone bill and contributes to the Sky and broadband as he has his own set up in his room. This morning we have had a discussion about how much rent he pays me weekly. I currently charge him £25 and he gets 3 meals a day, snacks, all his washing and ironing done, his room tidied and bed changed weekly. He has just told me that one of his friends pays £20 a month and another pays £30. These friends are at college but have part time jobs and actually don't warm a lot less than my DS monthly. He thinks I am being unreasonable to charge him £25 weekly but I think he's getting a great deal and would love to live somewhere for that amount and get everything done for me! He's currently saving up for driving lessons and a car and is as tight as a badgers bum when it comes to money but even after paying out his costs he is left with over £600 a month! AIBU???
