I remembered in a heavy rain night, I waited for bus to come back. Suddenly, I saw cat wearing a red scarf, which id the rain beside bus stop, and then it said to himself: “This rain is too heavy, It’s not easy to live in this world. ” A cat can speak? I was stunned at the time, and it stared at me, and suddenly disappeared before my eyes as if it didn’t exist. Later, I designed a custom pin for black cat according to memory.
