For me- it's her "happy" actions. Macie gets sooooo excited when I walk through the door- she spins in circles until I pick her up then she lays her head on my shoulder gives me hugs and kisses.

I wish I could bottle her enthusiasm! It doesn't matter if I've been gone 5 minutes or 5 hours- I get the same warm greeting every time.
And the very best part.... she only acts that way for me! She gets excited when other family comes in, but not like she does with me!
