Jordan: I love your sweet heart Landon.
Landon: I don't have a heart!
Jordan: You do have a heart.
Landon: NO! I DON'T have a HEART!
(We had a similar discussion a while ago which ended in "I DONT HAVE BRAIN!" :)
A few days later Landon was sitting in the front room with me playing and he put his finger in his mouth -- then after thinking a minute said quietly "I think I can feel my heart going all around in my body!"
