This really gets my goat but I’m not sure if IABU hence my question. So here goes. If I invite family members to something happening in advance, say up to 3 months (think family get together/Christmas do), the response is often along the lines of “we don’t know what we’re doing yet on that day”. Surely if you don’t already have a specific commitment then you just accept the invite, put it in the calendar and then nearer the time, if something else comes up you say “sorry, I’ll be at Avon’s that day”? What are they waiting for before saying yes? A better offer?? It happens every time! Surely you do now know what you’re going that day - you’re coming to mine.
YANBU - it’s rude and they may as well say they’re waiting on a more exciting invite
YABU - perfectly normal response
