I feel your pain....   I remember doing this as a kid..  We were at my parents friends place and they lived on Sydney Road in Melbourne and it is a very busy loud street... I was in so much pain that I did not even think to open the door with my other hand... I just screamed and screamed....   Being the street was loud it felt like hours before my parents actually heard me.. But I think it was only minutes either way it still hurt as Allyp says like a bitch...

Hope your finger is feeling better

OUCH... That must of hurt like a bitch... Oh man.. That reminds me of something my sister did to my mom when she was younger.. My sister was getting out of the van and she closed the sliding door.. and BAM my moms fingers were there and boy did she ever swear lol. I did the same thing to myself... but with the car, didn't realize my fingers were there and i closed the door on them.. boy if i could swear i would of!

I hope your finger gets better soon! Put ice on it, it will keep the swelling down!
