My friend once told me a story about how his kindergarten teacher singled him out for not drawing a bunny correctly. As an adult, he was a very funny, creative guy in many ways, but said his incident had a big affect on how he felt about himself in regards to his drawing abilities.
Whose to say what is right or wrong creative wise? Especially to a kid at such a young age. True, some creative efforts will be better than others, but it’s important not to forget that the act of having fun and being creative is just as important as it is turning something out to be a masterpiece.
