I don't understand it.
I am the only person in my circle of friends who doesn't have any of that. I remember, a few years back, one of the girls in the crew being a little offended that I had no interest in what she or the others were posting on Instagram or whatever.
It was like, lady, I am not above jerking off to pictures of my friends, don't get me wrong, but I have porn already, and the advertising there is less insidious.
I don't care about your selfies?
