I'm sort of similar but I don't "like" awkward silences...I just don't think they are awkward. I can go a long time without saying anything too. I kind of like people that I can be around that don't feel the need or pressure to talk just because we are together.
That being said, I do love a good conversation! I can discuss subjects with people forever. But if I don't have anything to say, I rather not just make up something just for the sake of it. Also, I prefer listening anyway.
