I say afternoon. I usually have some kind of a small snack around 3, which I call my “afternoon snack”. Usually it’s even healthy! It’s amazing how fast bananas and apples disappear in our house. If you’re doing something elegant or fancy, and want a “technical” name for it, I would still call it brunch. That’s what we always have on Christmas and Thanksgiving (I mean the Thanksgiving and Christmas meals are always called brunch). I don’t know. I vote we make it officially called Lupper or Sunch or Dunch or Dupper. Take your pick.
