A parent (parent A) sends out a text, obviously to several people, asking if anyone can have their dd for a sleepover in a few weeks time so they can go out for the night.
One of the recipients (parent B) replies, immediately (because they just happened to have their phone in their hand when the text came through), and says yes, we would love to, we have been meaning to ask her for ages.
3 hours later, parent A hasn't responded to parent B to say thanks and confirm.
Parent A is waiting for a better offer - am I right?
And is that rude?
