People have told me I am hard to converse with, because I don't always reciprocate or I take a bit longer to respond then normal. My body language doesn't always convey what I am feeling and thinking. e.g. I don't look at people when they talk so people think I am not interested in them. This isn't true at all. I am actually listening.

Small talk is extremely difficult. If it is a topic of interest, I can talk without much problem.
