I have few mugs
Porcelain mugs
All alike, same in color
I pick one and prepare coffee
Cannot distinguish the one used before
All were alike, same in color
I wish to make one my favorite
But any mark I make would be artificial
How I wish? A natural mark would separate one
Today I observed one with a slight difference
A minor crack at the brim
The mugs are washed
A mishandle would have caused
It is not ugly
It is no less useful
Naturally made, just a slight crack
Now both useful and notable
It is now my favorite mug
