I had a huge crush on this guy in 9th grade and I'm pretty sure he knew. He was in my gym class where all the "crush staring" happened, haha, and we had to run around for about 5 minutes, no stopping. As soon as I passed him, I tripped and fell right in front of him... he kept running staring back at me. At least he didn't laugh ... and later that day, during another activity, he fell right in front of me except I stopped and stared for a second and then kept going. Haha, so that's my most embarrassing moment but at least it ended with our falls being even!
