Snail Story...

It was raining the other day in Manila, and I and my friends were having coffee near the stairs where we usually use to drink... As it was raining, somehow a snail has crawled along the steps. We were looking at it with much curiosity as how it had climbed all the way over there... After sometime we returned to the same stairs for another round of coffee and found that it had climbed just two steps from where we saw it before... I was just wondering, was the Snail very slow or is it that I'm taking frequent breaks... :)
