Open Question: What would cause me to develop a foot fetish for only one girl?

[feedcrawler]

I don't feel turned on when I look at any attractive girl's feet, but I do when I see this one girl's feet. The first time I experienced it was on a school related trip my sophmore year, I just happened to see her feet while we were on the bus. Now any time I see her I immediately looked at her feet, but I don't do that to any other girl. Sorry if this is a little confusing or vague, and thanks for reading.
