Eh, perhaps they weren’t sure if they would absolutely want company for breakfast? And now they do. Sometimes plans change last minute, why does that have to be such an offence to you?
I would absolutely hate if my friends were like this. With us we can always cancel, rain check, or “hey, last minute but I actually now have a spare ticket” without all throwing tantrums at each other for not being considered even earlier.
You’ve now been considered, you’ve been invited. You’re being a drama queen.
