Oblivious

Hey, all:

I have what is formerly known as Asperger's Syndrome, now known as "Autism Spectrum Disorder." Due to this, I have a very difficult time understanding social cues. There is a man who I am attracted to, who admittedly is also attracted to me, but we are unable to be together for various reasons. He's hot and cold a lot of the time and fairly inconsistent. He went from ignoring me to speaking to me again the other day by way of criticizing someone else within their earshot. In order to get my attention, he grabbed right above my elbow from behind and spoke directly into my ear. What was that all about?
