Signs that a lady likes you

HOW is her action different?

Seems like the excitement is in YOUR mind and unless she or you make a move to find out if there's something more, then it stays in your imagination.

Err, they have whole books written about this subject.

The best one I ever saw was 'Undercover Sex Signals' by Leille Lowndes (which is about indicators of attraction), and there's plenty of stuff on Youtube too.

But basically you need to know how she normally behaves around men (because some women flirt as a way of manipulation) and see how she differs with you (then again, she may differ with you if she finds you an easy target - see why it's difficult to advise?)

Then see whether she gives off multiple indicators (one off indicators aren't reliable) : eg :
- preening (playing with hair is the most common)
- leaning in towards you (many different versions of this)
- stands closer to you than she does to others
- her feet are pointing towards you
- pupils grow larger when she sees you
- shows you her wrists or neck
- displays herself
- plays games with you with a cheeky look in her eye

- lots of different ways. You're better off reading a book or two on flirting, or looking up youtube as I mentioned.
