No matter how good you are at climbing, sometimes you get to fall.
One afternoon when the sky was cloudy, I noticed a gray wall jumper crawling on the ground. I thought this little guy was lost there. He always hangs out on the house's walls and loves to hunt ants or mosquitoes. Maybe he was unlucky; he slipped and fell to the ground. But he was still okay. He just needed to find a signpost and he could climb again and maybe take a rest. He lives on the cracks in my house's wooden window.
