The only thing I can think of is the whole childfree hatred of parental oversharing on FaceBook.

I get why people are annoyed by it... not everyone wants to hear about Little Billy or Suzy's daily trivialities. But on the other side of the coin, not everyone wants to hear about the trivialities enjoyed by grownups either. I'm sure folks inwardly groan when I post a cute picture of my cats or a snap of a completed sewing or food project. Then they do what I do and scroll past.

And the string quartet still opens the tear floodgates for me. :3
