Pizza with the Principal

My amazing son received the "Principal's Award: Pizza with the Principal" this semester and went in a limousine to lunch with the other recipients from his school and his principal today.  I'm so proud of that little guy.  This is the second time he's gotten acknowledged - the first time was when he was 3 years old in preschool.  Back then, I didn't let him go in the limo (I drove him myself and had lunch with everyone) since he was so little and there was no car seat for him.  Today, he went like a big boy with the other kids....without Mommy.  Big sigh.... how can he be growing up so fast like this???
