This morning on my way school I was deep moved by what I saw outside a bank. An old man

was counting his money in the front of the bank while suddenly a young man came running

and knocked her down. To make things worse, his money was lying in all direction. In no

time the people around rush to pick the money up while the old man stood here, not know

what to do. Surprisingly, everyone gave back the money they had just picked up. The old

man counted the money again and found that not a single bill was missed. To my great joy,

there are now a lot of nice people in our life. It’s true that honesty is more important than

money!
