New Hand Sign

Surprises happen on yesterday nite. Yishion played with the car key's. Suddenly, he pressed the alarm button and the car sound loud. He throw away the key and hug mummy tightly until I off the sound. Then, I tell him "Pah Pah" - in Mandarin by showing the hand sign of tapping the palm to the chest few times. Then, I bring him upstair to our room. During he played inside the cot, I ask him how is "Pah Pah". Surprisingly, he repeat the hand sign to me.... I told daddy, but he not believed me until the next morning, Yishion show the sign again when we ask him.
