Warning - this is trivial.
Husband's family are coming to us for Christmas for the first time. SIL text me a few weeks ago and asked should she bring dessert, which was appreciated, but they are travelling a fair distance so I declined the offer and asked what sort of thing would they like.
SIL said family favourites were sticky toffee pudding and pavlova. So it was agreed I'd make those and today I got all the necessary ingredients to make them.
Husband gets a text tonight from SIL saying she has a shop bought sticky toffee pudding and pavlova to bring!
My take on that is that it's rather rude, and basically saying she doesn't trust my cooking!! My husbands point of view is that she just wants to help out. I don't see it as helpful as it's not what we agreed.
