Once upon a time a Flight Attendant worked at the 1R door. That Flight Attendant was me.
On my last pairing I had a minor clutzy moment. I had to open my door in order to empty my garbage cans, and noticed it was rather heavier and hard to push open than I was used to. But I got the door open no trouble. When the time came to close the door, however, I had a hard time pulling it back. It was very heavy, and didn't seem inclined to budge. The mechanic was nearby, and mentioned that the door needed to be fixed, as it had gotten very stiff, and offered to close it for me.
I am a stubborn kind of person, and when someone tells me I can't do something, it usually makes me want to do it more. So the door said "No, I am not closing" and I replied "Like hell you aren't, I will MAKE you close!"
The next thing I knew I was hanging out of the plane, only holding on by the door handle with my legs swinging ten feet above the ground. The mechanic was nice enough to pull me back in, but the massive bruise on my leg will serve as a reminder of one of the most important lessons a Flight Attendant (or Pilot) can learn.
Sometimes you just gotta let the mechanic deal with it.
