I find some people LOVE being miserable! That is the only way they know to communicate. Those are toxic people and no matter how you try to ignore them, they do pull you down. I just avoid them like the plague.

I had a family member that always spoke to their family in sarcastic tones and they responded in sarcastic tones, even to the kids and the kids to them. All conversations were sarcastic. I pointed it out to them and asked what the deal was. Thank God I brought it to their attention and they have worked on it and now they talk like normal people to one another.
