pat - // I doubt Portuguese parents would do it. Children are out and about in Mediterranean countries in the evenings. The English seem besotted with putting kids to bed early even on holiday! //
I entirely agree - as the Butlins' system shows, British culture has long been for parents to enjoy their evenings without their children, unlike their European counterparts who enjoy their children all the time.
Our oldest girls are in their forties now, but when they were under-tens, we would usually take them with us when we went out to eat in an evening, and we got used to the twin situations we encountered - one was that they would be the only children in the restaurant, and the other was that we would be openly stared at for doing something so unusual as eating out as a family, after seven in the evening.
We always enjoyed going abroad, where everyone else - apart from the British of course, did what we did, which was enjoy our children's company, and witness the by-product of them being comfortable eating in restaurants, and knowing how to behave, and order easily as adults.
I think things are better now, eating as a family is far more common than it was when ours were small, but it's taken time for that to change.
My take on it is that the Europeans simply like being with their children, and don't see the need to pack them off to bed in order to relax and enjoy a glass of wine.
