I don't want to pay for my son's lessons.
What is your reason for not wanting to pay for your son's lessons?
I want him to use his own money.
It's too bad you're being so stingy with your own son. Help him pay for the lessons.
Dude, he's a boy and he should suffer for it. I don't agree with all this gender equality nonsense.
Helping your son pay for lessons is your responsibility as a parent. When your son is grown and able to make money on his own then you can start thinking about weening him off of needing to ask for money. Right now however he needs you to support him.
