Call me a bad parent but I'm not going to let my son sell a concert ticket he has.
Why don't you want to let him do that?
I don't agree with him selling it after he begged me for weeks to buy it for him.
That is logical. He shouldn't be trying to sell something you bought for him anyway.
I'm a capitalist and the sellers aren't lower than me. I buy and sell things every day.
If he doesn't want it you can sell it but he shouldn't profit off a gift from you like that.
