We were invited to a small cookout a while back. It was a very last minute invite. It was about a 45 minute drive. Half way there, we called to ask if they wanted us to stop and bring something. They rattled off a list which was basically the entire menu! I swear! They asked us to bring all of the meat for the cookout, drinks, condiments, bread and even a few side dishes.
We turned the car around and went back home. Didn't even call to tell them we weren't coming.
Good for you! Who wants friends like that anyway?
