That was a terrible reaction; you relentlessly kept giggling, pointing, and laughing, which distracted him from the story. You even made him turn away to focus on you. Why can't you just sit still and be quiet and allow your Dad to get into the story? That would have been a genuine real reaction. How could you expect him to cry when you are laughing and being a complete distraction. This is a major fail. Bagsak ka talaga. Palpak ka naman e. Booo.
