Just a couple of things that have cropped up recently and a conversation with a friend.
A man at work "needs" time off to take his wife to a hospital appointment. I don't know what it's for and neither should I, perhaps it's something she needs emotional support with.
My parents are becoming a worry and probably should have support but wouldn't dream of letting me (or a DGS) take them to an appointment.
A friend's younger and fitter mother won't ever go to any medical appointment alone, so friend has to take her.
Another friend recently changed our plans to take her (married 30yo) son to an appointment about his severe toothache.
It's never occurred to me to ask anyone to come with me, last time I called 111 for advice they sent an ambulance and I got a taxi back from A&E in the early hours. I'm not saying that's the right thing BTW, I didn't want the fuss letting anyone know would have caused.
