Others I hate:

1. Any vague posting designed to get attention, such as, "Oh, so sad." or "FML" No, I will not ask what's wrong.

2. Hospital pics. SIlly me, but if something is serious enough that I require a hospital bed, posting a picture on social media isn't even on the top 1000 things I'm concerned with.

I'll leave it there because I could write an entire article on this too...oh, wait, I did, LOL.
