Our grandson, same age, is now living with us,

That truly sounds win-win.

So, be impressed, my condo neighbors started a Mahjong night last week, and tonight was the second session. Only one person knows what she is doing and she is teaching the rest of us. I won the first game tonight! Of course I had to check with her to be sure I was reading the card right because it is absurdly complicated, but she goes from person to person giving advice and answering our endless questions. It is more fun than I expected. None of us are at all competitive so it is a lot of fun.
