Blush much? Snot too much!
I was with two of my crushes (yes, not one, but two!) and I started laughing. When I laugh really hard my nose starts running a little, so I grabbed a tissue to blow it. After I blew my nose, one of my crushes goes, "um, I think you need that tissue again...you got a little something right there," and he pointed under my nose. As it turned out, I hade a HUGE snot ball hanging from my nose. I WAS MORTIFIED!!! But I kept on laughing anyway as if it didn't bother me...
