I think the little girl is a tough SOB, dont let go with the one hand
You dont really see screen doors here, though out in the country near pig or other animal farms they might be a good idea to keep flies out.
Where my sister lived they used some form of fine masked net that had a magnet assembly / zipper like seal in the middle, so you could just push thru it and it would then close on its own behind you.
Also strange here as most Danish houses dont have aircon either, so opening doors and windows in the hot summer days are pretty normal.
If Danish the little girl look old enough to cycle the couple of miles to and from school, and old enough to already know some times life throw a curb ball at you, or in this case a freak gust of wind.
Perhaps this will change, Danish parents are getting more and more protective of their kids ( in some ways ) so kids are not as tough as back in my day.
And in my day we had to take care of our self, and there was always the chance the Americans or Russians pushed the button and turned us all into ash.
Today people thing the cold war is a prize war between 2 companies that make icecream.
