The normal body temperature of the human body is about 36 degrees Celsius. Your almost cold body tells me the fact that you are dead all the time.
However, you are still smiling at me, you can talk, you are emotional, and you are not so noisy. I watched you pick up a cup to drink water, eat... I watched you do every ordinary thing...
It's clearly right in front of me, clearly within reach, but why, why do I feel sad?
