A Blind Man

A blind man was begging on a new york street side with a board written, "i am blind, help me". Once a guy passing that side saw him, he took his board and wrote something. From that time the blind man got heavy collection, many people started giving money to him. Can you guess what that boy wrote? He wrote, "today is a beautiful day but i can't see it"..... The way of expressing can change many things.
