My sil just told my husband and I that she booked him and her fiancé on a flight for a mini vacation. It was a surprise for him, but this is the first I have heard of this too.

It was very nice of her and a lovely surprise for him, but should she have not discussed this with me first before deciding for herself that we had no other obligations to attend to during the time of the vacation?

Yes! It wasn't right, if you have given us all the info.

Yep, that's all the info. She requested to speak to us both together and then told us the news. But just because she told us both together doesn't mean that it still makes it right that she just when ahead and booked the tickets without consulting me first to see if we had no other obligations coming up during that time.

Should I say something to her or just leave it?
