Then one day, I overheard(无意中听到) a classmate saying: " My mom is ② ____ on business today. Nobody(无人)is cooking for me. What can I eat? I am hungry(饿)now. " At that moment, I thought to myself: " How lucky I can cook myself!" Then I finally understood why my mom asked me to do all the things on my own.

Mom, thank you for everything you did for me.

Love,
