I don't get how being nice and not ignoring a girl implies leading said girl on. This has happened to me a few times and is always awkward. Just yesterday I was at a party and a girl pulled me aside and asked why I didn't call her after the first party, then tried to figure out why she wasn't my type. Sigh.

Guys have to deal with this all the time, and I think most of us can usually tell when a girl is just being nice vs being interested. Girls don't tell every guy that advances on them whether or not she likes them and why they feel that way, so why should I have to?
