I've paid my dues.
Why do you feel you have paid your dues?
I went to jail for 1 year so I think I paid my dues.
I'm sure that was tough, but it's good that you were willing to take responsibility for what you did. Hopefully after spending a year in jail, it changed you and made you realize what you did was wrong.
Nah, I'm just glad to be out.
I hope you're not suggesting you are going to commit crimes again. If you do, you will very likely end up back in jail. Wouldn't you rather live a free life outside of prison?
