Is TOO Smart a BAD Thing?

Well, I am very upset today. Colby was signed up to go to preschool and last week we got a phone call saying they needed him to come in and be tested. Sure, I get that. So today we went and he tested on the level of a 6 year old (he just turned 4). I was thrilled........until they told me he was too "high" for preschool. So now I am trying to explain to my son why he can not go to school even though his heart was set on it. Don't get me wrong. I am so happy he is so smart, but now he is suffering because of it. No he doesn't NEED to go, but he really would have enjoyed it. My heart broke for him. It's not the first time and it won't be the last time, but this stinks!
