Ds told my mum what he wanted to do, who he wanted to invite and what he wanted to eat. I had already agreed to all the things he told her about, and deflected the impossible, difficult or unreasonable requests.
My mum then suggests other things that bear no relation to what he has just said, most of them involving dragging 5 children, two of whom have never met her or my dad all around town for no real reason whatsoever.
A large part of my agreeing to what ds suggested was that it was at a place that was free to enter for adults and we would just pay for the train rides for the children. Then if the mums of the four guests wished to attend with their 4 year olds they wouldn't be out of pocket. if they want a couple of hours off, we will pop the kid in the people carrier and drop them home a couple of hours later.
My mum was surprised that I would invite the parents (and I think suffering from social anxiety about- shock horror- having to maybe talk to somebody), completely neglecting the fact that I wouldn't send ds unaccompanied to a party.
So am I unreasonable to expect her to just say (even if it's a lie) "that sounds lovely dear, I will have a great time".
