"Hi"

Yesterday Joseph was outside our front door . I heard him say "hi!" to somebody/something. He's always saying hi to people we pass on the street. (Unfortunately half the people don't return the politeness.) I turned around to look and saw him crouched down in front of the flowers at eye level with a beautiful butterfly. Unfortunately it didn't stick around long enough for me to get a photo, but I thought it was the sweetest thing. Who else do you know who takes the time to say hi to a butterfly?
