Why are people so unkind?

I caught a bus today, I haven't done that for a while, I'm more of a train user these days. Anyway, I was enjoying the trip, looking out the window and daydreaming when the bus pulled up at a stop ... and the driver proceeded to very rudely tell off the woman who had mistakenly rang the bell to early and wanted to get off at the next stop. Then when she got off at the next stop he yelled out after her "next time try to get it right so you don't inconvenience all the other passengers!".

My pleasant trip was shattered and I reckon hers was too. How humiliating for her to be yelled at like that for making a simple mistake. I was so pissed off with the driver. I was tempted to go and ask his name so I could make a complaint about him ... but then I was scared he'd yell at me too.

I get so mad when people are nasty for no good reason. Why do they have to be that way, it just brings everyone down.
