I am a ridiculous romantic, and although I've fallen in love with people I didn't initially feel more than passing interest in, I've also fallen head over heels in love with people the first time I set eyes on them. (So sue me. I'm a Leo.)
Some people would probably say that love at first sight is an absurd idea, but sometimes, you "just know," not after being with someone for a while, but as they catch your eye on the subway, at a cafe, or at the laundromat.
Do you believe in love at first sight? Has it ever happened to you?
