MIL is 81 and in rude health, if getting a little forgetful sometimes. She lives in a lovely village surrounded by lots of friends, one of whom she is particularly close to and they see each other most days.
Her friend has a daughter who lives about 150 miles away and when she comes to visit, her husband will normally drive her half way and friend or friend's husband picks her up from there and brings her back here. Then they repeat the same arrangement on the return journey.
Friend has been a bit unwell recently and has asked MIL to drive the 75 miles to pick up her DD. I really don't want her to do this. Apart from the fact I think it's a bit of a piss take (MIL already does loads for her friend as it is), it'll be dark, majority of the journey will be windy country roads and although MIL is fit and healthy, she normally just drives from her village to the shops and back and I don't see why, on this one occasion, the daughter can't either drive herself (she can drive and has a car at her disposal but 'it's too far'), or she gets the train this time.
I can't offer to do it as I'll be working that night. MIL really isn't keen on doing it be feels that she has to to help her friend out. I am trying to convince her to say no and no, I don't suppose it is any of my business, but I am not at all happy with the thought of her driving all this way, on her own, in the dark.
