I find that I can Tell when some one is kidding or whatever, but I reply or take it litteraly because I just see it as a natural response to answer any question or statement truthfully, even though I know that they are kidding. I'm not good explaining my thoughts but the gist is "I know your sarcastic but I will reply as though it was litteral because that's just how I roll." any one else like this or can you really not detect sarcasm at all?
