Yes, Reinvent and IAG. It was much the same as you describe in our family too. My parents had their time to themselves. IMO it is very important for couples to have those moments, whether at home or by going out somewhere together. You are right IAG, seeing one's parents having happy times certainly makes children feel safe and happy too. I can remember my mother ruffling Dad's hair as she passed by his armchair. Just a simple gesture but the memory still lives with me.

Surely the OP and wife could have an at-home dinner to themselves and make arrangements for the son to visit friends or neighbours for a few hours or even overnight. Then again, and just a thought, perhaps there is some reason why the son cannot be sent to someone else's home for a few hours/the night.
