I'd be that one guy who you never knew at all during high school but could recognize his face instantly. [spoiler]I shit you not, there was this one dude who I knew like this. Everytime we crossed paths, we'd say to each other "you're that guy!". We'd had some class together I think back in 6 or 7th grade and couldn't exactly remember, but for about 2 years in high school, we said that every time we encountered each other, literally. Then he transferred or something, so I was the only guy left... Now that I think about it, I wonder where that dude is. [/spoiler]
