In the small rural midwestern town where I grew up, we ate breakfast, dinner, and supper. When I went to college (same state, population was 40,000 vs. 3,000) we ate breakfast, lunch, and dinner. I was made to feel like a bumpkin many times when I'd talk about having dinner at lunchtime.
OK, that reminds me......is supper the evening meal or is dinner the evening meal? We have breakfast, dinner, and supper here.
When I used to live a little more north, we had breakfast, lunch and supper.
