"How Does She Knoooow You Love Her?!" (Name that movie!)

If I've done any (or maybe all?) of the following things with/for you, that's how you know I love you.

Sharing sweet treats. :)
Giving special nicknames.
Talking about important things and really silly random things too.
Asking for advice.
Giving lots of hugs.
Spending time doing nothing together.
Writing little notes.
Confiding my fears and hopes for the future.
Laughing and singing and dancing!

If I don't love someone, they get none of that stuff. Haha! To the ones I love, thanks for loving me too!
