Input: Text: so i was leaving the cafeteria at a university i was visiting after breakfast, absolutely dying. hangover? check. a couple hours of sleep? check. still waiting for coffee to kick in? check. alright. good. entrance to the building has three sets of glass double doors, and i'm headed to the middle ones. then this girl walks in- i know her from being "that super hot girl i met one time". so she's going past, and surprises me with "hi heathenhammer!"

shit, she knows my name? naturally i play it super cool. i smile and mumble out a "g'morning" and as she goes past sneak a glance at that fine backside. damn. she's turned around. there's eye contact, but definitely a smile. nice. it's a good day. i'm starting to feel golden. i glide right through those double doors and stride out into the morning light. determined, confident, and magnificent. 

except there is no middle door. there was a window. so my face turns into a mallet for the glass pane's gong. after i've finished reeling from the hit, i hear her laughing at me. she's laughing so hard that she can't even breathe. she even makes an effort to ask if i'm alright, but literally cannot. so i brush myself off and, after a brief pause, loudly say to nobody in particular "good. that was good. very, uh, bracing. who needs coffee, right?" and vacated the area.

anyway, i just went past the building. the fucking grease mark from my face is still there. maybe it will save the next poor bastard.
