Colp has it, but with the addition of crispy bacon.
Supper is not a meal, its an evening snack usually before bedtime if you’re the civilised sort that has your main meal around 17:30 and not later in the evening like 20:00 or later, as you’re not going to have the munchies at bed time. Supper normally consists of something like a crumpet, ideally with loads of butter and Marmite.
For me dinner is a posh or more formal event, so lunch for lunch, tea for evening meal, supper if I feel like it. But if i’m going out or having people around and making a more formal big deal its a dinner whether its a lunch dinner or evening dinner. The time matters not, there is no right time for dinner time.
