Man Child: Bert's the same age as Ralph and Melissa, both already married. They all attended the same school, the same grade along with Cedric Sneer. They all graduated from college. So, all of them must be about 25 to 30 years old. Also Bert doesn't live at his own home, Ralph and Melissa let him stay with them. However, almost every chapter we see Bert playing dangerous antics and acting as if he's still a teenager, if not a kid.
