One day last summer when I was watching my great niece and nephew, I rushed out to my car to get my coffee before their Nana left. I got my coffee, pushed the latch on the door, closed it, started to go and realized I couldn't go. A split second later I realized my thumb was in the door. I thought of yelling to Mary for help, but figured it would take longer than unlocking the door myself. Of course once you release the pressure you get hit with the the pain. My thumb was instantly black and swollen. This was in early Julyl and my thumb nail is now almost grown out to normal. Funny thing is I am normally very careful about car doors because when I was a kid, I accidently shut a toddler's finger in the car door.
