Reading this got me to thinking about how Alasdair sees the world. For example, I was trying to teach him to look both ways before crossing the street on the way home one day. We would get to the corner and I would say 'Watch for cars'. I soon learned that his interpretation of this was to stand on the corner and wait for a car to come along, no matter how long it took, watch it go past and then cross the street.
We went to the new playground at Assiniboine Park yesterday. What an amazing place! Alasdair was nervous about the swings, but he enjoyed climbing up to the slide and playing in the sand and water. He thought that the human-like frogs playing instruments were monsters. I don't know where he even learned the word monster, but I suppose he's kind of right about those frogs.
