Hair as evidence

Bro cut his hair in the toilet, thinking that he washed off all the evidence.

I went into the toilet, and found there were quite an amount of short hair on the floor, couldn't be mine right? Hahaa! I thought he shaved himself botak because in a few weeks time he is going to be in the army! Heh heh. But no! I still see his hair, and asked him why he cut his hair. His reply was "no, er, how you know!" Hahahahaha. Omg, I think i'm trained to see such tiny stuff. Like in the clinics, our measurements are measured in mm, not cm! Kudos to being in this course! I don't know how bro was looking, obviously there was still hair on the floor what!
