["When I was younger, in a lapse of judgement, I stole chocolate bars from a shop I used to work in. I was caught. I felt terrible. It wasn't like me at all. I wish I could undo my actions.", 'I think many children including myself stole things before they were taught it was wrong to steel.', "That's true. I wasn't really a child though! I was at university! We all have little devils inside us, I suppose."]
I would not beat yourself up over the mistake. We all make mistakes even when we are older and should know better.
I was once caught stealing from a shop I used to work in. Chocolate bars. I couldn't believe my own actions - I felt terrible.
