Mr. Brown is short-sighted (近视的) but he doesn't wear glasses, because he thinks it's not cool to wear glasses.
It is Saturday and it is fine today. Mr. Black likes sunny days and he wants to take a walk. He puts on(戴上) his black hat, takes his yellow bag and then goes out of his house. He walks on the street and looks around. The sun is shining and the birds are singing in the tree. Mr. Black feels very happy. Suddenly, a strong wind blows away his hat."Oh, my hat! "Mr. Black begins to run after(追赶) it. He runs and the hat"runs", too. Mr. Black feels surprised. An old man shouts at him from a window.
"Hey! What are you doing? "
"Running after my hat! "
"Your hat? You are running after my black cat."
