You gotta chill, some days i feel pretty pissed at the world in general but not every person is like that obviously. Its a meeting of wrong intentions or wrong time or wrong place, thats all. Sure its become a much brusque place to reside but believe me, our decency and politeness is a choice. Letting it go because we think everyone sucks for those momentary periods of irritation makes no sense – its a lose lose situation potentially for everyone. I have seen people’s lives change profoundly from small acts of kindness and curtesy. Dont let a few straw moments make you so bitter that you lose track of the bigger picture.
