This cracks me up. It reminds me of a time, that I was INVITED BY SOMEONE ELSE, to join her and her daughter for a birthday party/lunch thing, and ended up finding myself being the deciding factor on where we were going to have the party. Between the daughter not wanting to put us out with undo effort for her, thus turning down going to a place like Chuckee Cheese, to the mother not being able to climb stairs due to an injury, and thus unable to go to a gaming/restaurant on a 3rd floor, to about 3 other options that they both "I dunno, I'm fine with whatever you want"-d their way out of, I found myself on the phone, suddenly being the deciding factor.
And I flat out told her "...ok wait, YOU called ME to join YOU for this event, how the fuck did *I* end up being the one coordinating this shit?!" which made her laugh guiltily, because my wife and I have given her shit for all the years we've known her, about acting like that.
