It seems Joe struggles with the reality of convention; he wants a big family but not the day to day mundanity of it. In a normal year, they’d all have been on at least one extended holiday abroad and been at their Santa Monica house. That level of escapism gives the impression of not being entirely satisfied with what’s around you. He seems to be a man that’s always searching for a high and needs the next goal or adventure. Not always a bad thing but quite tiring for a spouse.
