Today my wife brought my niece back home from work. Her name is Jin Nee and she is 5 years old. We went out for late lunch together with my son's friend. The boys obviously were not used to having a little girl around them and the 5 years old was very curious and talkative. After having lunch we went to do some banking and went home. In the car, my niece start talking a bit and my son was annoyed so he asked his mum to ask his cousin to keep quiet but somehow my wife was angry with my son because she said he was loud and disrespectful whereas I thought it was his normal level tone and I intervened. Some how what I heard is different level of noise for my wife. This is interesting as I realised when we said we are all different, it literally means that and down to the perceive noise level which can impact our emotions. Of course later on I got my ears full from my wife via Whatsapp which sounded even louder than sound wave thru the air :)
PS: I did had a talk with my so about respect and understanding the behavior of younger children when we reach home one on one. After all we were all young once upon a time and we learn from our experiences which my friend said were mistakes in a much nicer way.
