The other day I went to the park for a walk after supper. when I saw a newly painted chair, which looked very comfortable with a natural white color, I felt like sitting on it. Then I stepped ahead and sit down. A cardboard on the ground caught my attention. I picked it up and found something written on it: "Wet. Do not sit." I stood up hurrying back home and pretended to be as calm as nothing had happened, ignoring the acquaintances' laughing greetings: "I like your zebra outfit!"
