What's My fault?

This post of mine have connection with the post entitled "shit".
I was so angry when you treat me like that.
I don't understand why should you do this to me.
It's not my business rather.
When I greet you, you made don't know.
When I pretended that I can't see you, you got mad with me..
What actually you want me to do?
Finally, you talked to me what's going on today,
But should I believe you?
2persons with 2 different story..
Which one to believe?
Well, it's none of my business, I think I shouldn't care so much..
Maybe it's time for me to wash hand on this topic!!
I have much more things to concern about especially my own feeling..
However, I just hope that I at least know what's my fault!!
