I don't know where you got that "family had fun staying indoors" when that's not the experience of a lot of us. Read the thread about the kids bored to death and dreading Sundays because they has nothing to do.
Playing board games, cards, watching films and documentaries together, drawing, painting
that's my idea of hell, and my kids would go nuts if that's all they could do. They can enjoy a bit of quiet time because they do other things first.
Nature walks are 'boring' well, they are?😂
Doesn't it occur to you that a lot of people are active, need to be active and it's the opposite of a modern thing.
On one side people keep banging on that kids in the past used to be outside, running, walking, climbing - and never home but on the other side, some posters pretend that kids must stay home pottering around doing nothing all weekend.
I also think too many kids are put into afterschool dance, music, activity clubs.
As opposed to..? Clubs were cheaper when I was younger, so we all used to do a lot more after school sports!
Between sport tournaments, clubs and parties, I dont' have to organise anything at the weekend, my kids are busy. So were my parents.. It's not a modern thing.
Again, we tried the quiet life during lockdown. Never again.
