Somehow

From talking with someone yesterday, I realize an old understanding that i got from my grandfather, Allah rest him in peace, who told me that each of us do shape based on the things that the person believes is the best one. A grumpy person might have a belief that his or her grumpiness is something he or she must do as a defense's of a mechanism to avoid them from getting hurt. While someone who is so cheerful actually its another mechanism in protecting the person from nosy people, problems, or themselves.

Just like other creatures on this Universe, we do have a mechanism device to protect ourself from getting something that we dislike. But unfortunately we get deceived by our inner side that somehow we could not find the path into the real of us behind the mechanism devices that we have been applied for ages. So, who are we actually?
