Re: sisterly affection....don't make me laugh

How upsetting for you vampire! You must be fuming ! Has your sister come over for the party? If so, she should be the one sitting in the main restaurant. Do you have the nerve to arrive early with your DH and children and 'innocently' claim some seats? You will not want to upset your mother, but if things are awkward you must make it plain that you are not to blame.
I hope the occasion goes off well despite the 'oversight'.

Have you checked with her, vq? I don't know how old your children are, but we include teenagers as adults for bookings as they eat adult meals, anyway. Do they have the names of every person going? If not, it could be four others have been forgotten and if you're there on time, there'll be another group who don't have seats. I hope they can sort it out so you can sit together - most dining rooms can squeeze a few more round a table if they need to.

.....assuming your sister is here for the event!

vamp, I'm so sorry . Here, have a shoulder to cry on.

I hope you phoned your sister to "check on the time it starts" ?

It is possible that it really was accidental, or that someone you thought would be there can't come. Though you know your sister, of course.

Oh Vampire! I bet you are hopping. I am sure it wasn't intentional. I hope it is all sorted out in the end. Perhaps your sister and her family could sit at the other table?? I do hope, despite everything, your Mum has a happy family day.
