I love how this show depicts a coming of age story for all parts of adulthood. Brian has a peter pan complex that gets him into a lot of trouble but for all the reasons he is constantly pointing out, getting old kinda sucks. Being in your 30s is kind of annoying. You cant exist in the same spaces you used to without being thought of as embarrassing, and if you choose not to go the whole suburban babies route, there aren't a whole lot of places for you to be with people your own age.
