over the rainbow

yesterday,

after the heavy showere, there was a rainbow !
...the rainbow soon disappeared.

poor, I forgot to take a photo because it's too amazing.

I was in a train then, and I heard school boy talking to his friends.

"Does the rainbow encircle the globe ? I believe so"

his friends laughed to him saying but

boy, I can say you tell a truth.

.... although I don't know you pass the sci-exam or not :p
