About done after a long day and while doing the pocket check panic because your moto key is nowhere to be found. Slowly realize that you probably left it in the bike. Have another panic attack because some one probably stole your bike since you were kind enough to leave the key in it for them. Get out to the bike relieved that it is still there only to realize you left the key on and your battery is dead. It's cold out and it takes a good 4 tries to push start the damned thing, usually with an audience.
This happened a couple of times until I got one the "Remove Before Flight" lanyards. Who am I kidding it still happens occasionaly.
