Dear Mom, We had a nice time in the park last week, Mom, but you left the day before yesterday. Where did you? What happened to you? When we were together, we went shopping, flew kites, went swimming ... You bought me a T-shirt in a store. You helped me with my homework. And you made sandwiches for me. We also slept together every night. You never said you would leave me. I began to look for you when I found you left, but I failed. Mom, thank you for teaching me so much. I hope to see you again. It's time for bed. I miss you! Yours, Jim From the passage we know   _  .
