Heart

This cute little exchange occurred between Sasha and her dad.
Sasha was examining the pockets of her father's jacket.
Sasha: Dad, what's in your pockets?
Dad: Nothing, they're empty
Sasha: Put something in them!
Dad: Okay, how about you put a kiss in my pocket for me? That way I'll always have a Sasha kiss with me.
Sasha puts a kiss in her dad's jacket pocket.

Then later, my husband told Sasha that he was happy he had her kiss in his pocket, because he had her kiss by his heart all day at work. She grabbed him by his collar, pulled him close, and gave him a kiss on his heart.
