Yelim, 

Thank you for writing about dinner at your house. I especially like the part where you talk about how your father tells you to eat vegetables, but you and your sister still don't eat them. Remember to pay attention to the tense you are writing in. Decide if you want to tell a story in past or present tense, and then try to be consistent. I made some corrections in your story and highlighted them below:

My mom says, "Set the table". So I stop studying, stand up, and go to the dining room. I bring the water and spoon and chopsticks. Also I put the food on the table. When my parents eat first, me and my sister eat next. We talk about our school and what we did today. Sometimes my father says "Eat vegetables", but me and my sister don't eat vegetables. After we finish dinner, we bring the dishes to the sink. 

Thanks again!
