Wondering About Something

Judy, over at Patchwork Times has a post today about friends inviting them to dinner, at their own house, and that got me to thinking.  

It brings up an interesting point to question.  And I ask it primarily from my own perspective based on my own experiences over the years.  I remember when I was young, that people would go out for a drive and just pop in to visit friends or relatives.  And then when I was out on my own, I used to do the same with my friends.  Granted, back then, while we did have telephones, we might call to see if folks would be home, but not always.  Folks didn't have to wait for an engraved RSVP'd invitation to come for a visit.  Life seemed more hospitable.

Here's my question: Whatever happened in society, that we no longer have drop-in guests?  Has society changed or have I?  Is my view of the past skewed?  I was thinking it was just that my hubs & I have become somewhat reclusive, but when I look around, it seems more the norm now, that people don't drop in without that specific invitation.  Is that true do you think, or is it just in my little world?  Have things like social media and cell phones made it such that dropping in for a visit is no longer 'normal'?  I'm sure it has had at least some affect on it.  Or, maybe it's just in this suburban environment in which I live, or my own nature as I've grown older.

What do you think?  What is it like in your area, amongst your family and friends?
