Annoying Gratitude?

I noticed today on facebook a friend posted "I'm grateful you didn't post what you're grateful for today." She doesn't read my blog so I'm pretty safe in saying it wasn't directed at me but it also made me wonder. What is it about someone else's gratitude that can be annoying? Maybe she was being sarcastic? I would take annoying gratitude over some status updates I have read.

I have a friend who ends almost every update with the word "sigh". I have had to block her because I can't take the negativity every day. I don't understand the constant depression. Is there nothing in your life that makes me smile? Sigh.

I have another friend who constantly brings up topics to spark in depth conversations. Playing devil's advocate ALL the time? I've even been lured in to make a response and immediately regretted it remembering that his sole purpose is to watch the dance between all of his friends.

Another friend just posts nonsense. If we were still 14 I would find his status updates funny. Instead I read them and wonder how, at 37, his sense of humor and his friends haven't changed AT ALL.

Maybe I'm just boring and easily annoyed myself? Maybe I am facebook friends with people I was not actually FRIENDS with and those are exactly the reasons why. I do know that I wouldn't be bothered if some of these people were more grateful. I am also thankful for those friends I have that are.
