I think when I was six I stole my friends toy.
Why do you think that you stole your friend's toy?
I'm scared of admitting it, but I'm pretty sure I was a kleptomaniac around age six.
I'm sure you know that it's not okay to steal things from people. I hope you have learned not to steal since then and are not still taking things that don't belong to you.
No I still steal things from time to time.
So you still have that issue. You should go find a therapist who can help your with your compulsive behaviour. Stealing is not a nice thing.
