Those days emptiness is the correct word describing the state of my mind. No inspiring words, no interesting thought and chances are my mind is too blunt to reactivate. Now all I need is likely a good grind stone to sharpen my thought.

It, however, reminded me of a story in the past: on the way back home from a vacation to Hai phong, I and my Mom eagerly went to a local market to buy a grind stone as this area is wellknown for this product in Vietnam. After a series of bargaining we happily brought home a large, smooth and strange blue grind stone which, according to the seller, was a very good one.

I then spared no efforts to grind our knifes just to realize that instead of doing its natural task, all of our knifes became "shining mirrors" and here was what grandad said "stubborn-headed, your lovely stone is just too soft to be a grind one" !!!!???
