How do you know if a zodiac sign cancer girl likes you?

It's really hard to tell. You have to be very attentive to her every move when you're with her. She'll only give you one sign, so you have to catch it- and catch it fast. It might be a certain look, or the way that she snuggles close to you. Whatever it is, there will be no more than one sign, because she'll feel like you saw the sign and simply chose to ignore it- meaning you don't feel the same way. She would never try again after she feels rejected unless you seriously are just not getting the hint.
