On the east coast its way less 'appropriate' to interact with strangers so friends are a more limited set, necessarily brought together by more than mere chance. The cultural differences are so fascinating.

Yes I can go on about that too. Friendships are harder to form but last longer and seem deeper on the East Coast. Here on the West Coast, you frequently have relationships and appear to be deep friendships and then you just drift apart and never connect again.

It's sort of like the smiling thing at a mega scale.
