A snowflake - You can make a difference.

“Tell me the weight of a snow-flake”, a sparrow asked a dove. Nothing more than nothing”, was the answer. “In that case, I must tell you a marvellous story”, said the sparrow. “I sat on the branch of a fir, close to its trunk when it began to snow – not heavily, not in a raging blizzard, no just like in a dream, without a sound, and without any violence. Since I did not have anything better to do, I counted the snowflakes settling on the twigs and needles of my branch. Their number was exactly 3,741,952. When the 3,741,953rd dropped onto the branch, “nothing more than nothing” as you say, the branch broke off”. Having said this, the sparrow flew away. The dove, since Noah’s time an authority on the matter, thought about the story for a while, and finally said to herself, “Perhaps there is only one person’s voice lacking for peace to come in the world”.
