They got ticketed for having sex? Ticketed?
Very strange. They should be ticketed for being 19 years old in high school. I was in graduate school at 19.
How many grades do you have to stay back to still be there at 19 or do "tickets" keep you back?
And who would want to "get ticketed" with someone who is dumb as a box of rocks? So many questions.
1) The bell curve has two tails.
2) Unlike you, I followed a 'normal' academic career. I was graduated from High School at age 18 and from College, with BS in one of the physical sciences, at age 22 (Grad school followed a more unusual pattern). If this character is in his Senior year, he is at most 1 year behind.
