What if I'm thinking of giving my uncle back half of the change from the errand I ran?
Why would you steal from your uncle?
He's richer than Bill Gates!
It's wrong to steal -- from your family members or anyone else -- regardless of the size of their bank accounts.
I'm stealing anyway. I can't seem to stop.
Taking change from your uncle when he trust you to run an errand is wrong and he will likely know that you have done this. It's best to show him that he can trust you and simply ask him if you can use some of the change.
