i now have, um, purple hair.

the bugs in my bathroom are springtails, and now that i know what they are, i have been able to back burner my obsessing over them and boil some other interesting tidbits that have for too long not seen the light of day. like the tiny fine hairs that grow around my belly button. why do they grow slightly darker there? and why do i feel the compulsion to rip them out by the root? social conditioning? medication withdrawal? why?
