I told him that while he's here, he can't get a motorcycle. However, since this is a dirt bike, I'll let him keep it.
As long as he doesn't throw all his money into this project, I'll be glad to see him enjoy it.
However, if his whole paycheck starts disappearing, his rent goes up. I'm not letting him live here practically free unless he either (a) saves some money or (b) gets his teeth fixed. Or both.
Because I don't enjoy helping people who won't help themselves. And no, he doesn't read this blog.
