It's funny in fragmentary perception how we think we are the same person and yet we are completely different at different moments. For example we make different decisions when turned on sexually, angry or calm, in the evenings or in the mornings, confident or shy, hot or cold, hungry or thirsty.. We feel different and we think different when circumstances change. We have nothing in common with the person we  t h o u g h t  we were a moment ago.
