Dunno?

I dunno man.
I dunno how it is supposed to be.
I dunno why some people can be so determined. It's just sad to see their efforts being wasted.
I dunno why I can't do what I should do.
I dunno how to understand all the underlying actions.
I dunno why I'm such a coward.
I dunno why I can't seem to handle things well.
I dunno why I'm not firm. I can get persuaded quite easily.
I dunno why emo mood strikes again. Not supposed to.
I dunno..............
