How can you tell if she likes you?

If she likes you she'll let you know. Some girls will come right out and tell you. Others will show it by wanting to spend time with you and do little things for you. A few will be very shy, but you can watch and see if the girl acts nervous around you or tries to avoid you. Lots of times that means she's so in awe of you that she doesn't want to mess up around you and cause you not to like her.
