I want to make my comment based on what I heard during my undergraduate days. There is this Profesor of Inorganic Chemistry, that I have heard many people talk about. I heard there was a day he left his wife in the school and drove home, only to get home and remembered he was not with his wife. Also, have heard some saying that he forgets his car at a parking lot on some occasions and practically trekked to the bus station before he knew he brought his car. Although, I am not sure of the veracity, but somehow I think he acts like he forgets a lot of things and easily display mood swing.
Thank you for sharing this post with us again. I wouldn't expect less of such important discussion.
