Just wanted to comment re Downs Syndrome. A relative of mine was born in 40s with DS, so about the same age as Reggie. She lived at home with her Mother, father and siblings her whole life and by all accounts had a normalish life interacting with people and doing stuff.
As was common for those with DS she died as a relatively young adult but had a good life.
So the Reggie storyline is definitely ringing true with me. IIRC there were comments at first, but now people are.used to him. Even in the 40s/ 50s/ 60s people did just accept things after while even if sometimes made unacceptable comments at first.
I don't mine CTM being twee. I was VERY worried Lucile was going to end up under a bus earlier. I much prefer her going to the Dr and Jamaica and a happier 'ending'.
