I'm thinking of taking the store's money from the cashier after buying a candy bar.
Don't you think its wrong to steal money from someone?
Yeah, I'm sorry. I can't be taking my chances.
That is great that you have reconsider taking the money. Stealing is wrong and people will think you are being greedy. I hope you are happy with your decision.
I'm not happy, I'm greedy!
Being greedy is not a good thing to be. People do  not like others who are being greedy and do not want to spend time with them. You should try to be more generous which is an atttribute that people appreciate.
