Input: Text: it's been a couple weeks since i'd been to the gym. i got sick, i started a new job, life was generally being shitty and in the way. after some gentle encouragement from my girlfriend, i agreed that i really did need to get back on it and go back to working out.

cue yesterday, first day back to the gym. i had lost my old lock but i had the one from my locker at my last job so i just brought that with me. i show up, get changed, and work out.

when i get done with my workout, i go back in the locker room, grab my soap, a towel, and underwear, lock my locker and go shower.

i finished my shower, walked out and up to my locker, and my heart sank. you can probably imagine why.

my old lock was a combination lock. the one from my locker at work was a key lock. my keys were inside my locker.

there i stood, wet, cold, and in my boxers, staring at my locker and the empty locker room and contemplating my next move.

after a few minutes alone in the locker room, i realized nobody else was going to be able to help me (because nobody else was in there), so i braved the journey from the locker room to the front desk.

here's where it gets worse -- the entire gym is one big room, with mirrors around the perimeter. if you're in the gym, people can see you. it was late, but not late enough that the gym was empty.

as an added bonus, the men's locker room is the room second furthest away from the front desk.

oh, and i should also mention that i am quite an, **ahem** *portly*, individual.

so i walked up to the front desk, damp and in my underwear, and faced the (unfortunately) female front desk attendant. as if my luck wasn't bad enough, now somebody from the other gender was the one i had to ask for help, in front of god and everybody, in my underwear.

much to my relief, the gym has a set of bolt cutters which she lent to me so i could go get my locker open. i trekked across the gym, now looking more ridiculous than before, in my underwear, holding a bolt cutter.

i made it back to my locker, cut the lock, got dressed and walked back up. i returned the bolt cutter and made it a priority to get the fuck outta there as fast as i could. hopefully nobody that's in there tonight was there last night, but chances are i won't get so lucky.
