A man is sitting down to read the paper when he hears a knock on his door. Upon opening the door the man is confronted by a snail on his doorstep.
“Good evening，” says the snail， “I'm collecting for the snail benevolent fund. Would you care to make a donation？”。 The snail gets his reply as the man kicks him into the bushes.
Ten years later there's another knock at the door. Again， the man finds a snail on his doorstep. “That wasn't very nice！” exclaims the snail.
