Input: Text: okay, so this fu happened roughly a couple months back.

i was at a starbucks near school working with some of my classmates on a report that was due the next day. 

(yes, we procrastinated.)

a few minutes in one of my classmates ask me to go photocopy some handouts that were needed for the report.

now, at this point i should tell you that i don't exactly have perfect 20/20 vision but neither am i having too much difficulty with seeing.

so the starbucks we're working at has those clear glass-type wall things which made it pretty hard for me to tell where the door was. 

(you can guess what happens from here.)

so as i try to leave, i get a face full of glass wall and end up dazed for a bit, looking at my classmates shocked expressions and say "that's not a door" and proceed to walk out there, more embarrassed than i've ever been.

tl'dr: door was not a door, turns out it was a glass wall.
