Ok, I have some headcannons for the campbell trio when they're teens/adults
-Neil is always the tall and dad friend. Nothing can convince me otherwise
-Nikki actually gets into a lot of sports and takes agriculture classes during high school
-Max kinda gets a bit of a beard during his later years of high school, and he looks fine as hell with it
- Max becomes a camp counselor when he's 18. He claims he hates being a counselor, but he secretly loves it
-As for the other two, Neil ends up working at a science university and Nikki becomes a park ranger
-if anyone in the trio goes on a date/gets a boyfriend/girlfriend, the other two become third wheels and mock the other saying shit like "Now fuck!!" or "EWWWW! Get a room you two!" whenever the one with their date does something slightly romantic.
-Also Max gets into a smoking habit in his senior year of high school and David doesn't know until the day Max leaves for collage. And he gets pissed about it
-Max developed a crush for a girl just because of her boobs when he was a sophomore. Nikki and Neil teased him so much for it
And I can't think of anything else.
