HA! I *knew* I kept my toothbrush in my bedroom for a reason. John came out of the bathroom last night with a toothbrush going "Alright! Who's been using my toothbrush?" Hilarity did ensue because in fact the toothbrush was actually Ian's. So in fact John had been using Ian's toothbrush. Basically, they've been brushing with the same toothbrush together for god knows how long. So nasty.
Oh whatever, I know how those two are...
I share toothbrushes all the time. :D
