If I'm not feeling any particular emotions one way or another, I don't think I should be expected to have an answer to the "How are you feeling?" question.
If I try and force out an answer, I just have to take a super vague hint of what might be a feeling or notion, and expound on it until I can use words to describe it, and by then I'm just trying to label things that aren't there.
So I don't think I'm hiding from emotions. I certainly experience them. I just think that my emotions aren't doing much of anything a lot of the time, so they usually aren't pronounced enough to be made readily apparent to me.
