I'm simple, if I say:"...Hi, good morning,or/and good bye..." You should be happy cause I had been kind to you, not always I am in this world, I live most of the times in my world. So I may look serious, but this doesnt mean I dont like you, that's mean that I get problems here and there too. But of course, if you know that most of the time you will see me happy and smiling.
So enjoy me as longest you can. . .
