Ah, I have so many cringe-worthy memories! A few have stuck but most have long since stopped bothering me. I must be getting old!
I've vomitted in classes from kinder to uni, can't remember anything much about them now, or the blood noses, though I did once bleed on friend's textbook, yuck! I had my pants split at school and once at work -my favourite cords! I borrowed a colleague's spare jacket which was a dress on me, then walked home to change on my lunch break. None of the children knew, it happened as I was crouching down talking to a toddler quietly outside. So could have been *much* worse. I was a bit embarrassed as it was not exactly professional.. but mostly upset my pants were ruined!
One memorable cringe was also clothing related, and at work. When I first started studying to be an EC educator, I was on placement at a local kinder which was a 10 minute walk away, uphill there, downhill home. Wearing suitable clothing was (and is) a challenge to me as I was a 6EE. If that bra size doesn't mean anything to you - you are either very lucky, or bra size is irrelevant to you.. either way, younger me is jealous. Older me has too much else going on to care about cup sizes anymore.
Anyway. I went bra shopping, which in those days was a family trip across the city to the only lingerie shop that stocked my size, and they only did that because of me (though plastic surgery changed that). I spent hundreds of dollars for 3 bras, and then had to wait a week while they were altered. For some insanely stupid reason, while waiting, I went to Cotton On Body (clothes, lingerie store) with my sisters, and foolishly thought I could make bra sister sizes work to wear some of their pretty (yet hopelessly cheap) bras, since all the money at the lingerie store got me plain ones - which I didn't have yet.
The next day was a kinder placement, and I tried on the cheapie Cotton On bra, making sure it fit well, covered everything and whatnot. Well. By the time I was partway up the hill it had unhooked itself, which I fixed. Then halfway up I see one of the kinder teacher's sons on his walk to high school *just* as I felt the bra unhook again. So I hold my arms very very carefully to minimise chance the kid (13?) will notice anything, and as soon as he's passed my I fix the bra again. I then kept one hand holding the bra done up while pretending to rub my middle back as if sore the whole way into the kinder.
Once there, I tried desperately to figure out what was going wrong with the bra... 20 mins before the kinder session started I gave up and asked for help. There was a student teacher with us who was supposed to be "in charge" of things that week, so this problem was declared her job to deal with (we all got along really well). She checked and the hooks section had come unstitched, not off completely, but was so loose that they couldn't stay done up. So we used masking tape wrapped around the ends to hold it done up "enough", which I adjusted and added to every break until I could get home and change.
Lessons learned : *never* wear cheap bras, and *always* test new clothing for actual use, not just walking-around-in-my-room use!
