I love it when mine do that, it's so sweet. Freddie will slick his topknot down and whistle Beethoven to me or, if he's in a really good mood, he'll draw a deep breath and say "pretty baby!" Johnny just sings and runs toward me and sometimes shoves Freddie out of the way. It's a competition to see which of them loves me most.
