Since Beth and Lyn asked, here's an explanation of the reason I didn't know my true birthdate until I was a senior in high school. I mentioned it in my post about PattyK's birthday.
When I was 4, the cutoff to start school was March 1. My actual birthday was March 2 so I missed it by one day. Apparently my mother felt I was ready for kindergarten at 4. So, she got out an eraser and erased the 2 from my birth certificate and then put it in the typewriter and replaced it with a 1. Therefore, I was accepted to start kindergarten when 4 years old. They didn't tell me for fear I might say something at school and had a fear the school authorities would put me back a grade where I should have been. I don't think that would have happened as I was always a good student and near the top of every class. Even into high school they never told me. One day as a senior, I was looking at my baby book and saw a newspaper clipping announcing my birth that my mom had put in the book. I saw it said my birthday was March 2 and asked how they could make such a mistake. That's when they told me the truth. I never asked them when and if they were ever going to tell me. I was due to go off to college is a few months and assume all my paperwork has the wrong date. To this day, March 1 has a special place in my heart. It's like having two birthdays.
It's also fun because 3 generations of women in my family all graduated from college a year earlier and a year younger than usual - my mother because she finished high school in 3 years, me because I started school at 4 years old, and my daughter because she skipped a grade.
