Much like his name suggests, Narcoleptic Nelson was a genuine narcoleptic. At any given point in the day, his head might nod forward and he would find himself asleep. This no doubt caused problems for him while walking and driving, but we only ever witnessed him nodding off while he was using our patron computers. Each week, on the same day, Narcoleptic Nelson would arrive to use a computer and the staff would begin making wagers as to how long it would take the man to surrender to the sweet grasp of Morpheus. It usually took no longer than 10 minutes.
Narcoleptic Nelson's computer sleeping habits were really not a problem for us otherwise. No, the only hassles we endured as a result were usually doled out by other patrons, who didn't appreciate having to wait to use a computer that was currently occupied by someone who was fast asleep. The usual complainant in such cases was our old friend Parka, however, a person whose happiness in life we couldn't have cared less about. Our point to him was twofold: A) while we don't encourage it, we technically have no policies against sleeping in the library; and B) we give each of our patrons half an hour on the computer and if they choose to use their time asleep it's all the same to us. Parka was not amused. We were.
Narcoleptic Nelson has not been seen in quite some time. I hope this means he's off being the subject of an intensive sleep study, rather than the less-pleasant notion that he crashed his car on the way there.
