“I don’t wanna share!”

It’s funny coming from a family where your siblings are so much older than you. So much older that they didn’t even grow up in the same house that I did. So in a way, I was raised as an only child.

Which means what?
That I have a closer relationship with my parents? Maybe.
That I don’t share well? Possibly.
I get jealous? I don’t know.
I get upset when things don’t go my way? Depends.
Do I pout when someone says no? I guess I do.
Maybe receiving the undivided attention of my parents all my life has spoiled me a little rotten.

I guess I do have a problem with someone else touching my things. I suppose I do have a problem sharing… So how do you go about breaking habits like that?
