It takes all sorts to make a world. Everyone have different personality, style and think.
I like to communicate with people. When you communicate with them, you will find that was so interesting.
For example, in the morning, when I encounter a familiar person, I will greet him. Then I will chat with him about his recent status.
When I encounter an unfamiliar person, I still say hello with him, but I will not say too much with them.
I am an easygoing person and I like to make friends. But, sometime I still suffered a rebuff from some unfriendly people when I greeted with them.
Such kind of people, I would not have to deal with them further.
But this is just a litter part of people I have contacted. I believe there are still many friendly people in this world.
My motto is there are still a lot of good people in this world. Trust me, and you will make many friends too.
