We saw "Space Chimps." When the lights dimmed, Jackson turned to my friend Beth and said, "Miss Beth, turn the lights on!" And after a little while, he saw a woman walking up the steps to her seat and shouted out, "My seat!" The selfish little guy was making sure she didn't take it. Throughout the movie, he kept pointing to his seat and Beth's seat, saying, "My seat. Your seat." He got a little restless near the end of the movie, but thankfully it was just over and hour long and he lasted through the entire thing.
I remember doing this same thing with Katie when she was around two. Her first movie was "Clifford's Big Movie." She surprised me, just as Jackson did today. Sometimes I underestimate my kids.
