One day Mon said to me "I love you. son"

　　I was very happy that day and went to school.

　　6 o'clock in the afternoon, i went back home.Dad was also back and there was a big cake on the table.

　　I asked him "why there is a cake? can i eat it?"

　　Dad answered "No.Mom should eat first."

　　"why?"I asked again.

　　"because it's your mom's birthday"

　　then i remembered mom said "i love you" to me in the morning.

　　and she said "i love you"to me.
