I think that there is at least one certifiably crazy regular patron at every public library. We have lots! There's the dumpy guy with the 4 or more hot/cold bags that he carries with him every day (my boss opines that's where he keeps the heads). Then there's the guy who comes in every Saturday morning who asks for the weekly preview for the Young and the Restless, and whose wristwatch's alarm goes off at 10 a.m. He doesn't shut it off.
And we have our fair share of bipolars, schizophrenics, etc. who call and come in and make life interesting.
One of our regulars, whom we have dubbed "Fuzzy Top", hasn't been to the library in over a week. We realized this today. Until now, she came in at least once a day to use the computers (and to ask if anyone had delivered a $1,000 check for her to the library or if anyone had turned in a wallet. She also liked to trade her guest pass for another one, because "they are tracking this one" or "I can't have any with 3's on it" or "this one has a folded corner").
I hope she's okay. Actually, I kind of hope she has been admitted for psychiatric treatment, because it seemed like she was going downhill last time I saw her...
UPDATE: She's back. Apparently she took off nekkid down the road and got put in the hospital for a few days.
