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.

it was mom's birthday,but i didn't know that.

and she said "i love you"to me.
