There is an art to this. Everyone wants to let the world know that people find them desirable, but they want to do so in a way that doesn't feel like bragging. Cue the stories about how much of "a creeper" the guy was, how "awkward" you felt after she approached you, or any other way you can spin the story to be more than the just bragging that someone found you attractive. We get it, it's nice when someone flirts with you, but there are few stories as boring as tales of someone else flirting.
