Attention to all humans that have interacted with me in the past week and a half! You have (possibly) been exposed to head lice. Best guess is that they were hiding in or on skin and oil detritus caked to a stuffed elephant my son was carrying around, so it's possible that I'm the only one that got affected. Still, check yourself. Neph and Katie especially.
