Sweet and creative ways to tell my friend I like her?

It makes a girls heart melt to hear a guy sing and play the guitar for her. It is really romantic. Don't write her a song because that may be coming on a little strong, but find a song that expresses "like" and not love. Sing it for her. When you are done tell her that you like her and that maybe one day you will be able to write a song about her! She will melt! Flowers too!
