Some minutes later, I got a text message from her, saying "Happy Birthday on your 39-years day? I am only 36 years!" What? I haven't written that! Where did she get that from?
My sister explained to me, it was the birthday-cake that talked and said that. Oops! I didn't know that the cake talked too! Because I'm deaf, I didn't heard that.
But my sister understood that I couldn't hear what the cake said.
She was happy anyway. :-D
