why do you think this? just curious.
is your social circle made up entirely of academic conversation at all times?
I think you're right that it depends on the person.. because I 100% believe you that your wife is intelligent and fits in just fine with formally educated family members.
I guess it just seems that GENERALLY speaking, those who did not go to college don't have a lot in common with those who did.. at least in my age group that seems to be the case.
Of course, a lot of my insight comes from the fact that most uneducated people I know are from Central, had children at 18, never leave the town, and have no concept of the world outside. I am aware that does not mean all uneducated people are like that
