Friendship in suburbs (like Desperate housewives)

[Villavic]

Yes, I'm hooked with this show, too.

But I have a question. Is it usual to have close friendship at suburbs, like the 4 ladys of this show? I mean, I've been in US many times, and I agree with other (foreign) people who have been in suburbs, that people don't make friendship at neighborhoods. Just a kind "hello", "good morning", etc. But they don't usually go to dinner to the family next house.

I realized that when I visited relatives in a NJ suburb, as I did with friends in California and Florida. I didn't see children playing in the street, my nephews weren't friends of their neighbors. They usually play at the school or fields, or they go to the mall.

Is it common to stablish friendship with neighbors, as I see in D.H.?

And what about Canada, UK, and other countries? (for the ledgies of the world).

Btw, in Peru is very common to make close friendship with neighbors, as to have close fights, too, ha haaa
