I've found the best way to deal with embarrassing situations is to make a story that everyone can laugh WITH you at. 'Course, it helps if you can see my facial expressions while I'm telling it. . .
My most embarrassing was at an airport (although I've had more than my fair share of embarrassing ones). I was suppossed to fly from Washington D.C. to Atlanta, but I missed baggage check by a whole five minutes, so I had to go on standby. One standby flight after another went by, until I'd been there for about ten hours, when the dreaded aura hit. I'm merrily typing away at my computer one minute, and the next I'm twitching and glitching my happy little self up to flight attendant, who's eyes flew wide open when I told her I was epileptic and about to have a seizure. It actually came out as more of a plea, "Excuse me ma'am? I'm sorry for interrupting, but I have epilepsy and I think I'm going to have a seizure. Is there someplace safe, with maybe a few less people around that I could go to?" It kind of made me feel better about my own feet when it took her a few minutes to get hers moving. Okay, it was more like 30 seconds, but it felt like forever.
Anyway, I just barely made to the restroom entrance, which fortunately was really close, when I hit the floor. Of course, they wouldn't let me get on the plane, and I was traveling alone, so I ended up getting wheeled through the airport on a stretcher and taken to the hospital, where they gave me enough Ativan and valium to knock out an elephant. Then, in my drugged stupor, I told the nurse I was going home for Christmas, and I was catching the next flight. She said, "We'll see" and left the room. So I proceded to unhook the IV and everything else, and was standing there fully clothed, with all the linens in the hamper, about to just plain old walk out, when she came back in. A friend picked me up and took me back up to the airport, where I caught the next flight, and slept through the whole thing. I landed safely, with no further problems (no big surprise with all the added drugs), but unfortunately, my luggage, with all my Christmas presents, did not land with me. It was a bad day, all in all, but I laugh whenever I see the nurses expression when she walked back into my room!
