Have you ever had a “friend” who gave you way too many “less-than-platonic” signals but then acted surprised when you confronted her about it?  What would you say about that person?

Um, yes actually.  Some people are genuinely surprised at how they come off to others.

Why is that a problem, though?  Why would you need to confront someone about their personality?  Would you confront someone for having red hair?  I would say that person is being a person: nothing more, nothing less.

Seriously, there are flirtatious people in the world.  Their mere existence doesn’t necessarily mean they’re flirting specifically with you.  They’re most likely just enjoying being who they are.  Some people just have “a vibe” (like some people are loquacious, like some people are reserved, like some people are loud, like some people wear colorful clothing, etc., and so on).

In the past, think of Marilyn Monroe and Mae West.  Currently, think of Toukie Smith and Jane Krakowski.  Sure, you could say they were or are just acting.  You could also say they were or are just being themselves.  What you can’t say with authority is that flirtatious people clearly have the hots for anyone or everyone that fancies them.

Unless you’re willing to risk finding out whether your friend actually wants you (i.e., by asking them directly “Do you fancy me?”), just assume they’re being themselves and enjoy the fun and flirty atmosphere they create.
