You sound similar to my mother's story. She was born in 1912 in Clearwater, FL. When she was 6 years old and ready to start school there were no other kids in the 1st, 2nd or 3rd grade so they put her in the 4th with her brother. After school he had the task to catch her up to the rest of the class. It was accelerated learning on steroids. The problem was she was always 2 or 3 years younger than anyone in her class. She was ready to graduate from high school at age 14. Grandpa thought that was too young for her to graduate so he arranged to have her take some secretarial classes for a couple of years and when she reached 16 they gave her her HS diploma.We were dirt poor and mom and dad both had to work. We had no one able to baby sit me. We lived in the sticks so to speak. Our local school had 8 grades in one room with one teacher. Though I was 2 years shy of being old enough, mom convinced the teacher I could do the work, so I got stuck in school 2 years early, which made me the smallest kid in the school. I hated school and it was even worse because I loved sports and being the youngest and smallest kid in the school, it put me at a big disadvantage. By the second grade, we had a regular school, but I was still the smallest kid in class till my senior year. By the time I was in the military, I was as big as most of the other guys and things started changing. Instead of being a runt, I was always the guy batting third. It did a world of good for my confidence, but I've always wished I'd of been the same age as my classmates.
Times sure were simple in those days.
