Humans are difficult creatures. Have you ever met with experiences where you wonder how some humans can be utterly unfathomable at times? Maybe it's the brain. It can make you intelligent but it can make you stupid as well.

Take this example. I was on the way home from work yesterday and as usual I had to cross the overhead bridge to my block. So up the escalator I went. There was this middle age lady in front of me. As she got off the escalator, instead of walking in a left arc, she verved left horizontally across the path of the escalator. (she's on the right side of the escalator) I was caught unaware. Luckily I braked in time and the first phrase that crossed my mind was 'WTF!'. This is one of few human behaviours that can really piss me off. A lack of ignorance and courtesy. I know there's this phrase 'Ignorance is bliss'. However, I realised blissful ignorance must be used at the right time.
