Riverwalk, yes, too early. We never had 'high tea' - only afternoon tea - growing up. It caused endless problems if we took friends home after school for 'tea'.
To us, it was/still is a snack between lunch and dinner (dinner - or supper - served around 7 - 7.30 pm). To other families, though, it was the main evening meal!
Yes, it was always just a snack for my children after school, though sometimes when they went home to other children's homes where they were given a proper meal. We always ate together at 7-7.30 once everybody was home.
Now my husband starts to lurk around looking for snacks in the late afternoon, usually savoury: nuts, crisps, sometimes prawns or olives. He has a glass of wine but if I did that he'd probably never get his supper!
