For weeks before our last WDW trip we prepared my very shy 3 yo DS for meeting the characters, hoping he would not be afraid. We repeatedly asked him, "What are you going to do when you see Mickey?" He would respond, "I gonna give him a hug." We spent our whole first day w/o seeing Mickey but just as we were leaving EPCOT we saw Space Suit Mickey. We were the only family around him. My little guy got up out of his umbrella stroller, head bowed, arms outstretched and slowly walked over to hug Mickey. We got the embrace in a snapshot but I don't need to see the picture, I will never forget it.
Also, a baby being born....even if it's only on TV.
