Thinking of you!

I thinking of you very much....I'm very funny when thinking about happy memory in  DN, Hue...That happy memory will precious thing in my heart. And recently, have a problem which I always think about it in my mind...from this side to side, then the other from this situation to other situation...But no matter how, I really want to know the reasons of it, I don't want to have any ambiguity about it. I believe I can overcome that serious difficulties.
