Sometimes when your dad is the loud, boisterous one the kid might be the opposite and be quiet and reserved
From what I've gathered Bisping's son Callum seems like a pretty level headed kid considering Bisping is his father
He told Mike that he can't retire until he fights Whittaker, that's pretty mature of a 17 yo who wants to see his father fight the #1 contender
He could've went along with Bisping and said, yeah, retire after GSP
For what it's worth, despite how obnoxious Bisping can be, he seems like a terrific dad that has raised respectful children
Hat's off to him for that
