I can't stop myself sometimes but I stole a phone.
Why did you steal the phone?
If you are looking for a rational reason behind this, this is my condition, kleptomania.
I'm sorry you have this condition, and it's totally valid that you can't control it. But you are still being a thief to people and that is very unfair to others who rightfully paid and owned their stuff.
Do you have any idea how expensive the phone is? I have to do it when I see one of these and they always get what they deserve.
Well if it is an impulse, you can take it to the police station or a mobile phone store and say you found it. That way they can try to return it to its owner. You should really stop before you get caught, have you tried therapy?
