Time
Dear Mr.G.
People always say time is something that can pass you without even being noticed. So it must be something that either has an invisible shell or a pair of long legs just like you. So that it can run fast , run, run run out of sight before you put your eyes on.
But I think time does prefer to sit still sometimes. Its big legs could get sore. And it also likes to have a cup of coffee and a donut in the sun alone like Mr.Okada.
