Guys subconsciously pay extra attention to you and tease and poke fun at your personality quirks
A classic move - guys tease and make fun of girls that they are actually interested in. This counter-intuitive strategy that hans't changed much since the playground days, and that's because it works. When a girl is being teased in a gentle way, she knows he is trying to impress.
Girls subconsciously ignore and avoid a guy she is trying to catch his attention
On the surface, this doesn't make sense, i know. But hear me out! Somewhere deep down girls know that a little mystery goes a long way and that a girl who is worthy attention shouldn't ever have to scream for it. This manifests - at conscious level - as avoiding or ignoring a guy a girl actually has a crush on. I know, we're the worse.
