A childhood belief about getting older

I used to believe that every time my teacher threw a birthday party for kids with summer birthdays, we were already another year older. When I was in kindergarten (6 yrs old), and it got to be spring of my kindergarten year, my teacher threw the summer birthday kids a birthday party (I was one of the summer birthday people) before school ended for the summer. I went home and told my mom I was 7 years old...She said, "No, you're not, you have to wait until August." and I said, "How long until August?" and she said, "Not for a long time." and I said, "Well, I want it to be August NOW!" and then she went on to tell me it just wouldn't work out that way... The same thing happened when I skipped from kindergarten to 2nd grade (I was in 1st grade after kindergarten, but for only one month, then they moved me to 2nd grade). My 2nd grade teacher threw a birthday party for everybody in my class that had summer birthdays (a lot of us!), so I went home again and told my mom I was 8 years old. I was soooo bummed!!
