I was always one of the youngest in my class. My birthday is very late in the year. I also graduated high school a year early and entered college while I was still technically 16. I got the occasional joke/comment about not being able to drink until I was a senior in college.

Being oldest in the class comes as a huge advantage and is making many American families "red shirt" their child by putting them in school a year later; and this making them the oldest child in the class all the way through.

Oldest. Got weird dating senior year.
