i've got a lot of compulsive behaviors and obsessions (mostly due to residual paranoia), but i'm by no means ocd, and i know it. it's annoying enough having to keep your (admittedly large) knife collection srupulously clean (read, near sterile) and razor-sharp (as in, you can shave your face with them) on the off-chance you'll get to use it this month, but it's not life-destroying. my friends used to bug out about this, but they just accept it's part of my quirks. and they're happy enough i bring my knives at cookouts.
i'm barely functional as it is, i can't imagine what it would be with full-blown ocd on top.
