My 2 boys were playing the game of Connect Four when my elder son (A1) got rather frustrated when his brother (A2) didn't quite understand the rules of the game and was randomly placing counters into the slots. He stood up angrily, spilling the colored counters all over the floor and shouted at A2 in frustration.
When I changed my questions to be more people-focused, my son is more open to answer them and even if he doesn’t know the answer, it prompts him to talk to people and make friends.
Do you have many difficult days at home, much more than you would like? I feel you, and I am no different from you, and I too have my fair share of difficult days.
