Nationality Crisis...and a Head-On Collision

So today, for the first time ever, I had to speak in Model UN. Except I didn't want to to. One of our USGs (Under-Secretary General) put me on the speaker's list.
Naturally, I was terrified. But finally, it was time to go, and the SG calls out:
"Ukraine is now recognized for 1 minute!"
I start walking out, and realize a new girl is also walking up to the front.
Oh dear. It seems we have a bit of a nationality crisis.
Now, there wasn't a doorway for me to hide in, so I had to stand up near the chair and awkwardly wait until they had figured things out. I was hoping that I might end up with a free pass from speaking.
No such luck. Everyone just giggled until they called decorum.
I said some generic stuff, and walked back, turning red in the face. Awkward.

Another awkward moment was about a week ago. Some friends and I were walking to lunch after another invigorating band session, talking about new levels of sharp-ness that had just been reached in the last number.
I had been looking sideways to talk to my friend as we walked, and we were approaching a sharp bend in the hall when all of a sudden my friend grabs my arm.
"Marena!!!"
"Whoa!!" said a deep voice...not anyone's I had been walking with!
I turned around and realized to my horror that I had walked straight into the lunch tray of a kid who sits behind me in band - a mere acquaintance of mine.
I managed to back up before I got a shirtfull of pizza, and managed to mumble an apology of some sort, attempting to avoid eye contact.
Yeap. I'm epically smooth
