Had to sort of have 'the talk' with mum last night about hanging up the car keys. Had it before and we agreed only short trips (<2km) in daylight and less regular. Now after this it's completely not safe for everyone. Feels bad, basically taking independence. She brought it up saying in a few days she'll be able to get behind the wheel again so in that sense it wasn't a sit her down and tell her something out of the blue thing.
I think one of harder things here is hearing her say 'in a few days' about a lot of things but the reality is things have changed permanently. In not saying anything when she says that I am giving false hope which I'm not sure is good or bad.
