Partner A & B agreed they would feed their child a bit earlier tonight after a hectic week of Halloween discos and clubs, then the grown ups would have a takeaway for dinner once said child is asleep.
Partner A picks what they would like from the takeaway menu, sends to Partner B before starting bedtime.
Partner B knows the takeaway is usually really quick midweek, but takes around an hour on a weekend. Partner B goes ahead and orders the food (including what was requested).
Partner A is unhappy that the order is placed before the child is asleep (and therefore may come before they are ready) and wants to cancel the full order. Partner B calls the takeaway to ask to postpone delivery, which they are happy to do. Partner A no longer wants the takeaway and is making a sandwich for dinner instead.
Is Partner A unreasonable?
