No I didn't. I moved out just after my 18th birthday but had been working full time for three years before then. I saved my money, my p's didn't need the money and they would rather see us save than pay them to live in their house. My sister moved out at 21..my p's gave her the ultimatum to get out or start paying board (as she had finished uni then) so she got out!
I won't charge my kids board unless we really need the money, or they waste their money. If they waste their money then I'll charge board but put it in a savings account for them so they have something behind them when they wake up to themselves and be sensible.
DH always says he'd rather our kids moved out and we helped them financially while they got on their feet rather than our kids paying board and living at home forever! He moved countries when he had just turned 17, me out of my house at 18 and none of our kids are welcome to live with us past the age of 25 (DH says 20, I say 25!)
