Tell her how you ADMIRE her. 
When she's upset. Hold her tight <3 Pick her over all the other girls
you hang out with. 
Play with her hair.  Pick her up, tickle her and wrestle!
Just talk to her.  Tell her jokes. Bring her flowers Just Because.. Holdherhandandrun. Just hold her hand. <3.....
Let her fall asleep in your arms. Tell her she looks Beatiful. Look into her eyes and smile :).
Kiss her forehead.  KISS her on the run.  If you want to be with her......
<3    Tell Her  <3
