A Halloween horror story

Somehow last night I managed to shave off half of an eyebrow. No idea how, but it's gone. Now, my eyebrows are white, so it's not that noticeable - until I darken them for work/being out in public. It'll grow back, right? RIGHT?! Might need to rethink my Halloween costume.

Sidebar: google "no eyebrows." Why are there 1000 images of celebrities without eyebrows?!
