[usr] I lost my car keys. I'm such a fool! [qst] [None] [bhv] I'm in a negative mood, please comfort me.
Happens to everybody. My girlfriend, who is the smartest person I know, has had to make 5 duplicates of her car keys because she's locked herself out so much. She's so forgetful because she's so efficient and on top of everything else important, that sometimes she misses the small things. Maybe that's true in your case, too!
I lost my car keys. I'm furious with myself.
