I was reading when my little brother rushed into my room. "I made paper airplanes, David! Aren't they cool?" Tex shouted, sending his plane directly into my head.
I was a bit angry. "Excuse me, can I have a little peace and quiet so I can read?" In fact, I was upset about the exam which I failed yesterday.
"Oh! I want to read!" said Tex. "Can you read your book out loud?"
"I don't want to read aloud," I said more angrily.
"Are you in a bad mood (情绪)?" Tex asked.
"Tex, just leave me alone!" I got up, making my way towards the living room.
"What's up, David?" asked my father.
"I'm in a terrible mood!" I said.
"I like organizing things when I'm in a bad mood," said my dad.
"I like cleaning up when I need a change in mood," said my mom.
I knew everybody was trying to help make me feel better, but I felt even worse.
Just then my friend Ollie stopped by. "Check out my new soccer ball. "
I stepped outside and said, "I'm too busy being in the world's worst mood to do anything at all. "
"When I am in a bad mood, I move," said Ollie. He kicked the ball far. "We ran and ran to catch it until it was finally stopped by a tree. That's when we saw a cute squirrel (松鼠) catch snacks from a bird feeder. "
"Whoa!" said Ollie. "I never knew squirrels could hang upside down like that. "
"Sure," I giggled (咯咯地笑).
"Hey!" said Ollie. "That noise you just made sounded a lot like a laugh. "
I smiled. "Possibly. "
"Of course, you do. Catch!" said Ollie. He threw the ball at me.
