I wasted $10,000 dollars of my dad's money on absolutely nothing in 1 day, and he has no idea I did it.
What would happen if he found out?
He would hate me for all the things I've done to him.
Oh boy.  It is not good to waste that amount of money so quickly and it isn't even your money!
I don't care since I've been wanting to do this since a long time.
You should find a way to pay him back - $10,000 is a lot of money! If you are that angry with your dad, you should talk to a therapist about what he did to make you upset so that you don't take it out on him by stealing his money.
