The other day, a 3-year-old and I were playing with dinosaur stamps (the kind you press on ink pads, not the kind you mail), and his imagination took off and he scared the wits out of himself. So I can just imagine what that kronosaurus would do to him. ;)
When my daughter was that age, she loved looking at dinosaur books and could tell you the names of every one and if they were "plant eaters" or carnivorous. I thought she must be ready for a trip to the museum and figured she would love to see the dinosaurs there. Wrong. When she caught her first glimpse of one, she screamed and jumped into my arms and damn near choked me she held on so tight. She said "Daddy --- it's going to eat me."
Three year old kids are not good a separating reality from imagination and the problem most of these Greenies have is they still have childhood mentalities.
