Within this last week
I witnessed a dissection of a real human brain from three feet away (and ate a yogurt oat bar during), lost about two hundred dollars worth of enzyme due to a pipetting error (this blunder took ten seconds to accomplish), had my lips bit (albeit gently) in a car at night, and had to bundle up because of an actual snow-fall (which is the second time since the beggining of September I've had to do it).
