If you want to pay her a compliment don’t go overboard and don’t make it about how hot she is.
Compliment her shoes or some accessory instead because that will show her you were paying attention to more than just her boobs! Don’t go where you’re not wanted or pop up out of the blue in her face: Make sure you aren’t going to scare the hell out of her before you start talking.
TIP…do this instead: The best thing to do is to WAIT for a signal from her to you that it’s okay to approach her.
Don’t just walk up or try to stop her, for example, when she’s texting on her phone, dancing with her friends or walking from point A to point B!
Don’t touch her right away and keep your distance – try to think of that Dirty Dancing scene with “this is my dance space, that is your dance space” and make sure you aren’t hovering too soon, that’ll just seem pervy and will probably scare her off.
