Leave her cute text messages. Kiss her in front of your friends. Trust her over everyone else. Tell her she looks beautiful. Look her in the eyes when you talk to her. Tell her stupid jokes just make her laugh. Mess with her hair. Just walk around with her. Include her in most things you do. Look at her like she's the only girl you see. Tickle her even if she says stop. Kiss her forehead. Let her wear your clothes. Let her know she's important. Let her take all the photos of you she wants. Kiss her in the rain. Sleep with her when she's cold and alone at night. && most importantly Be there for her.
