In my Human Bio prelim last month, this girl walked in late, sat beside me and just burst into tears - like, full blown body-wracking sobbing. No-one said a thing, so we're all grappling with the complexities of the phospholipid bilayer in silence trying to pretend that this poor lass is not having a (very audible) breakdown. Not so much 'funny' at the time, as it was painfully awkward. Hilarious now though.
