Take her to her favorite restaurant and go have ice cream and talk about girl stuff. School, Girls at school, boys. Do anything to keep the conversation flowing. If she likes to make things take her to a pottery store and let her pick out something she would like to paint. Or if she is the sporty kinda person take her to a gym or something and swim in the inside pool or something fun. Go see a movie. Anything that she likes! I hope I helped! Good Luck
