I'll give you a few.
Standing quietly just behind the photographer watching Mickey and Minnie pose for pictures with people. DD2 LOVES Minnie and we came upon the shoot - but they had already cut it off because it was almost time for the characters to have a break. The photographer looked a bit nervous telling me this - makes me wonder if they don't get complaints. But, I reassured him that was fine, and would it be ok if we just stood behind and watched - as DD2 just wanted to watch Minnie. She was SO good standing there quietly watching and not causing any distractions for the people getting their pictures taken. Every now and then she would do a shy wave at Minnie and in between families, Minnie would do a quick wave or blow a quick kiss back - lighting up the face of my little one. When the photo session was finished, they exited right past us and Minnie bent down and gave DD2 a big hug before walking by. I WISH I had my camera ready - but it was SO fast. The joy on my baby's face melted my heart.
Another one - The look on DD2's face when Prince Charming from Twice Charmed ran up the aisle right next to her!
And another - Laughing with DS9 SO many times, I think my sides still ache!
And another - laughing at DS9 saying "AAARRR me matey's" to everyone on pirate night and DD2 saying "AAARRR me kitty's", right behind him - we still don't know why she thought it was kitty's.
And this one - my little princess dressed as Snow White hugging Snow White.
