One of our neighbours is hosting a murder mystery for several couples in our cul de sac. One couple have a bf 6m baby. They have accepted neighbour's invitation and are having a grandma over to babysit. Neighbour is planning to wait for Gma's call and then she can just nip home to feed baby back to sleep if she wakes up and the murder mystery script can wait for 10 mins. Surely SWBU to expect the other 11 guests to just wait for her? V. unlikely she'll be only 10 mins. Host neighbour and I think she should decline invitation.
