We were watching a documentary on reptiles that we’ve seen before. One of the lizards they showed was the basilisk- the Jesus Christ lizard- and it can run so fast on its back legs that it doesn’t break the surface tension on the water and can run right over it (for up to 20 metres)- hence its nickname. When they said humans could do it too if they could take 300 steps a minute, Damien laughed so hard he nearly choked on his sandwich. I realised he was laughing at the concept of a human mastering the requirements to be able to run on water- rather than at the image of the lizard running on the water. It suddenly struck me this weekend how much Damien has grown up- that he would laugh at different things now than things hat are just visually funny.
