There again sat a snail

A man moved to a mountain top to get rid of the hustle and be alone.

One day he heard a knock at the door and no one was there but then he looked down and there sat a snail and it said "it is quite cold out here, can I come in?"

The man shouted, "NO, why don't you all understand I want to be alone!" and he kicked the snail down the mountain.

One year later there was a knock at the door and no one was there and then he looked down and there again sat a snail and it said, "What did you do that for?"
