In preschool, kids are happy to do fingerpainting, make stuff with modeling clay, color with crayons, etc. They're inventive and they don't seem to follow any rules. They take the stuff home and their parents think it's great, but it's not treated with the same seriousness as the three R's. Then as the years go by, the teachers start telling the kids they're doing some things wrong. A few kids get over those hurdles, but most decide that art is not for them and they stop doing it.
