When I was in seventh grade or so and pretty hefty, I had an appetite to match my size. My sister and I were out and about and I remember complaining that I was getting hungry. My sister told me to wait until we got home because she wanted to stop by her boyfriend's apartment and surprise him with a gift--just a sweater or somesuch--and with the gag gift she'd also gotten him, a pair of strawberry-flavored edible underwear with red licorice laces.
We stopped at the guy's house and he got a kick out of the gag gift, then set it on his bathroom counter so he could go try on the sweater. I couldn't stop thinking about that candy. Sure, it was candy in the shape of underwear--men's underwear, specifically my sister's boyfriend's underwear--but it was still sweet, sweet candy. They'd never notice if I went in there and just shortened the licorice laces a little.
It would've been fine if the bathroom hadn't had TWO doors. I locked one, but my sister, who knew I'd been too quiet and stealthy to just be making a normal bathroom visit, opened the door from the bedroom.
I was caught eating my sister's boyfriend's underwear. In my mind's eye, I can see the licorice strand falling from my lips as I opened my candy-stained mouth in surprise. It may not actually have happened that way, but that's how it looks in my memory--and you'd better believe it was BURNED into my memory.
There was also the time I got my period during my trigonometry final (yes, I was wearing a white dress; no, I couldn't leave the room for any reason).
Then there was the time I tried to hold in a sneeze and wound up farting as I was inviting my first high-school crush to a party (he declined).
Oh, and when my brother helped me move from my first apartment, he upended a nightstand and a "toy" fell out. That was just an awesome experience for everyone involved.
I think that hits all the major embarrassment highlights in my life thus far. I'm not including the various farts, nose-whistles, visible bra straps, mispronunciations, trips, falls, stumbles, and blunders to which I am prone. I'm a silly and embarrassing creature and somehow people still love me, so I guess it's not too bad.
Please don't feel ashamed or embarrassed. Wearing a bathing suit is the best time to eat ice cream--that way if it melts, you can wash it off more easily.
