The Dinner Invitation

Some years ago I was visiting some old friends in Ann Arbor, Michigan. They were not old in age just old friends.  I called a close friend that worked for the same real estate firm I did when I lived there. He invited my wife and I to dinner at his house. We agreed on a time of 1:00 p.m. My wife and I arrived a little before 1:00 p.m.. We had a great time reminiscing but by 3:00 we still had not eaten dinner. I was starved by 4:00 as was my wife. I did not say a word to my friend but came to the realization that we were invited to supper. He was accustomed to  the midwest ritual of breakfast, lunch and dinner. Growing up in the low country of South Carolina, it was always breakfast,dinner and supper. My friend did not know we were confused and we had a good time. Guess he could tell the way we ate through appetizers that it was time to put the bratwurst on the grill. Now I will ask, even in the south, when invited to dinner.  Will we be having dinner or supper?
