all about the moon

I love watching the moon. At this very moment, a half-moon is lurking over me. I enjoy watching it. I enjoy the idea that amidst darkness, the light coming from the moon brings in certain hope...

So i have surfed about some physical facts about the moon compared to earth which can be found at the latter part of the blog.

The moon is just plainly pretty to look at to.  It's ok to be in a romantic mood while looking at it. At this very moment, the halo that surrounds it makes me even fall for the moon, and at the back of my mind, I am hoping we are looking at the same moon.

I am talking to the moon right now. I am happy of its presence.
