I was 7, in 1st grade (In Russia, you get to 1st grade after 7th birthday). There was this girl, she was the tallest in the entire class, I kept running after her all over the school, finally cornering her in the ladies' bathroom.

I never dared enter, but kept at it almost daily, and lost sleep at night over her. Man, she was the first girl that I ever lost sleep over. I was a silly little kid back then...

Just before 3rd grade, I moved to United States, and that was the end of it. Funny how memories like that remain stuck with me... sigh.
