Silly situation here. A friend is driving quite a long distance to the village where my DM lives. This is really helpful as I look after my DM who has dementia. Friend's DF lives nearby so it's not massively out of her way but I think she is partly doing it to be kind and helpful.
Anyway, friend wants to leave at 9 on Saturday. The only thing is DH and I have marriage guidance counselling at that time so I can't leave until 10. I told friend I had to go on an errand so could I come later and now she says she will take me on the errand instead. I don't know what to say!
