What are the funny moments in Family with Children?

In one episode, it seemed that everyone had wronged Liu Xing, and then went to apologize to him and wanted to take him to the aquarium, but in the end, they forgot Liu Xing at home! ! I really just completely forgot about him. Liu Xingle happily got ready from the room and came out and said: I'm ready! But no one answered him... At that time, although there was happy music at the end, I felt very uncomfortable. I put myself into the role of Liu Xing many times, and then I became more and more aggrieved. Well, I don’t know if the director simply thought it was a funny joke at the time, or if it was deliberately arranged to mock the world. If it was the former, that would be terrible.
