How about I go ahead and steal my dads credit card to buy steam games?
No way! Why would you steal your dad's hard-earned money and spend it yourself?
It's not like he needs the money; I'm doing him a favor to make sure he doesn't spend it on dumb stuff.
Even if you feel like your dad spends his money on dumb stuff, that is his own prerogative because it is his money. You should not steal from your dad. It is wrong and you will get into trouble.
I can steal anything I want, loser.
No, I believe you really can't. You will eventually get caught, so do you accept any punishment that could happen to you? I think it would be better to help your dad learn the value of money by encouraging him to save it, and maybe he will reward you with some of it.
