Is just something i see with my how eyes, but not experienced by myself, my cousin's parents was similar to the one in this comic, after divorce every one of them get new sons from new partner and just left my cousin to him-self, i think the only reasons he don't "fall in the canyon" is for him paternal grandparents (at some point just the grandma, because the grandpa passed away)the only two that really take care of him trough all this story of the divorce.
You sure wouldn't think so listening to songs on the radio though, would you?
