I recently stole 175 dollars from my buddy.
Why did you steal money from your friend?
Not sure, I have made some bad decisions since my father died.
It is wrong to steal from anyone, especially a friend. Give the money back to them and apologize.
I can't go back and I don't want to give him his money back.
You can and should go back. How would you feel if a friend stole money from you? You should treat your friends better than that.
