Right, but my point was not intended to be specifically about A/C, but innovations that keep us from physically being with each other in general. You might argue that we know our neighbors MUCH less now because we don't see them nearly as often. Being forced out of our homes - in some cases to prevent ourselves from literally dying from the heat - may have made people closer and friendlier with one another. Of course I don't want to be in deadly heat - but I also wish I knew my neighbors betters, and for the anti-social, like myself, being forced to be around them may have helped.
