When I grew up and got my first job I had to start paying rent. My son is now working and I ask him for 20% of his monthky take home salary for rent, food (+ personal care stuff for him) and his mobile phone. I expect him to contribute to his clothes but I still get big stuff (new bed for instance). He tells me none of his workmates have to pay their parents rent. He has more disposable income than me. Am I out of touch and being unfair?
