Yep, ur not allowed to mess up the mess! lol. Sounds like my brother as well! Looks like hair paranoia knows no age. I remember I once brushed with my dad's hairbrush and my mom was like "oh no u didn't just brush with that!", little did I know what she was going about till my dad came home and found my hair on his brush :D
From then on...all male brushes were avoided...at ALL COSTS!
