I've stolen $2.50 every school day for the last five months
Why did you steal money?
My dad wouldn't give me money so I stole it.
I know you feel like you need the money, but it's very wrong to steal from your father. You will need to give the money back to him.
My dad won't miss the money.
That doesn't matter. Stealing is wrong, and continuing to do so will build very bad habits within you. Habits that will get you into serious trouble in the future.
