My family tells me they worry about me because sometimes the things they say bounce right off of me but the truth is I am an observer. I listen and pay close attention to the little things that interest me. I conceal my thoughts, go with the flow, and do my own thing.
As an addition, I don't remember what it feels like to be healthy anymore, as well as no pain. It's absurd how quickly you forget something so great, to the point that you're never sure if what you're living with is what's normal or simply something you've gotten too used to. Bah.
