I was a lanky 5'9", 125 pound 14 year old with glasses, braces, and a bad perm that was mooning around my bedroom with an enormous crush on a senior that was probably only nice to me because he felt sorry for me...
Of course, when I ran into him five years later and had morphed out of the "ugly duckling" phase, he was VERY glad he had been nice to me... Just goes to show you what goes around comes around...
