Speculating language
In the first photo I see a family who look as if .........
Everyone seems to be very excited perhaps because they have just arrived at the top of the mountain.....
I think the girl
might be holding a lunch party with friends, it could be two sisters and their boyfriends.
On the other hand they could be on holiday and having a meal in the garden of their hotel, maybe the girl in the red dress is a waitress.
