Ever since 'affordable' A/C & then A/C becoming the norm, it is almost rare to see people 'out' without a purpose . Have ya noticed how new homes have almost no front porch ? Back in the 70's ? decks became popular, but they're in the back yard & not as 'friendly' ? as a front porch. And how much time do folks actually spend on them ? Most have become a status symbol for that once-a-year barbecue .
With all the electronic communication, I phone / text this & that, cashless society, direct deposit , & now I-phone ordering grocery's ,in home entertainment ....we are losing our social skills , & IMO desire for human contact.
Even kids don't play outside like they used to.
