My DS is 3, but his favorite number is five. He also aspires to be five years old, because he's certain that he will achieve all his dreams at that age. He wants to be an astronaut when he's five, and has also asked if he needs to be "more five" for certain activities.
Also, we live a block away from an elementary school. Every day when we pass it, he asks if he can go to school there, and I tell him maybe when he's older.
The other day we were driving home and he says to me, "Mom, Grandma says I can go to school when I'm five." in this smug little tone. As though I had been trying to discourage him from going to school but Grandma was going to let him. LOL.
Another funny. I tend to be a bit forgetful. DS and I were in the car and reached the stop sign at the end of our street. I realized I had forgotten something, so I sighed to myself and turned around without saying anything. My DS pipes up in this bored little tone, "What did you forget, Mommy?" Apparently I do that a lot.
