Thank you @riverflows for the compliments.
You are very right, they are poor in expression but they are sensitive, when time comes they will cry out also.
I am glad you have such a beautiful connection with your daughter in law, it is so important to have a good chemistry specially in that relation. My Son's ex-gf, she was a gem but sadly things didn't work for them and I really miss her. Anyways it's their life to decide.
