I have really been struggling when people ask me "How are you doing today?"
I don't want to lie to them, but I don't want to tell them the truth or even really to talk to them.
When I know them socially or at work, I am trapped!
I am left saying "I don't know how to answer that question right now."
Which is suitably ambiguous that they don't know how to respond and they leave me alone, so I guess it is a win for me.
Maybe that is the key, just develop a large pool of incredibly ambiguous responses for all the incredibly stupid questions that people ask.
I will start working on this and report back.

My ambiguous responses to "how are you" are "OK" or "hanging in there" if I don't feel like saying "good" or "fine." Oh, I'm amazed by the people who ask how I am, reply to me, and then walk away. Why did you bother asking how I was if you don't want a conversation? LOL.
