Input: Text: i teach english as a second language in taiwan. today, i was teaching 21 rambunctious 10-year-olds. i decided it would be safe to wear a cheap belt with some pants from when i was larger than i am now, because i generally think that wearing clothes that i own to class is a safe thing. spoiler: i was wrong.

early on in the class, my belt buckle started to act weird. the middle prong started to dip under the belt and past the hole, for whatever reason. annoying, but not a problem. i'd retighten my belt, shove the prong in place, and carry on with my listen. my students noticed that i was fiddling with my pants, and offered a few snide 10-year-old comments. no matter. that was when the middle prong decided to give way completely. it clattered onto the floor, free from its belt master. the pants followed soon after.

of course, the class burst into laughter, as one would expect out of a bunch of 10 year olds who saw their teacher's underwear. i summoned every ounce of chill inside me to keep a straight face. i went to the roll of scotch tape in the corner of the classroom and started taping my tightened belt to my pants. i figured i could macgyver out a passable solution for the rest of the class. i was wrong. the tape gave way pretty quickly, and once again, my class full of hyper 10 year olds got to see my undies.

i was in scramble mode. i had to send to co-teacher to get hardcore packing tape. after mummifying my waist, that did the trick as far as keeping them up. it did not, however, convince the students to do anything other than remark on the hilarious state of my pants for the rest of the class.
