do i really like it?

I talked with a friend with whom I have spent more than 6 years. We know each other well that most of the time we are just one person. He used to say, "You are the only one on this planet that knows me." I know him since he knows me. As we talked and talked, some unexpected words burst out that I believed it was the first time he put me into submission of agreement. He said, "You never think of the postive side. You always got the negative point." I was stunned. I got a good command of talking back against others. But this time, I have no words! You know, NO WORDS!! What a shame!
Am I really like that? The answer is absolutely affirmative. One hundred percent yes!
Though sometimes I got some kind of surprises out of these miseries, most of the time, I am always in the boundless abyss of negative fators.
Those who don't truely know me take me as a confident person that knows nothing of the trifles and truth of life. They have totally gone off the track. Fortunately, he is not among this group.
I know I have no need to say any thanks to him.
I really got a deep affection for him.
