When it rains, caterpillars and snails love to crawl out from the grass to move on the wet pavement. The act of moving on the pavement is risking their lives, we always see many of them were crashed to death by the passerby. So, when raining day, we try to walk looking down to avoid crashing on them, or sometimes we will put them back to the grass to avoid crashing by the passerby.
