I was walking in the wal-mart parking lot, not really noticing that I was smiling, I am almost always in a good mood and some grouchy older lady asked me in a curt manner what I was so happy about, I replied that the fact I got up that morning on top of the ground was a good enough reason to be happy and kept on going. To me every day is a gift and I do my best to enjoy it to the fullest. Look for the good in everything as much as possible, and ignore the bad and move on.
People like that are a negative drain on society. I politely get as far from them as possible.
Maybe they have an issue that is causing them to be ill all the time, but guess what, if they keep that up they will be ill all the time and add alone all the time to it, no one will want to be anywhere around them.
People should wear the smile that God gave them more often, it makes them nicer to look at and will bring them happiness by attracting happy-positive people.
