Doors

I see a door and I typically have one of the following thoughts:
1. "Brrrr...it's chilly, I should close that door."
2. "I need to go in that room. Lovely, the door is open so I shall pass right through" (yes, that's how I think - always eloquent.)


When my girls see a door there is just one thought that enters their sweet little heads:
1. "I MUST SLAM THAT DOOR! "


Why? What is the fascination with slamming doors? I understood when they were about 9 months old and they learned how to close them. It was a new fun trick, but the novelty certainly should have worn off by now, right? They use to close the doors so sweetly and would peak around open doors with cute little smiles. Now - SLAM! SLAM! SLAM! I'm terrified of little fingers being smashed, but they just laugh away.
I'm at my wits end with the door slamming. After one slam too many and before I could think rationally I told Annabelle that the next time she slams her door I'm taking it off the hinges. Why would I say that???? It's inevitable that door will be slammed by days end and I don't believe in empty threats. Anyone know how to take a door off the hinges? I guess I have to learn fast.
