I think this is a sad or quiet picture. It shows two girls waiting at an airport. They are standing at a big window, looking out at the runway.
One of the girls, the smaller girl, has her hands against the window. The other girl, who is about eight years old, is also standing quietly looking out.
There aren't any planes on the runway, only some service vehicles and trucks bringing fuel or water or luggage.
I think the two girls have been waiting a long time for someone, maybe their mother or father, to come, but there has been some delay.
There must be someone else with them, because they are too young to be in the airport by themselves, so maybe the person who is taking the picture is also waiting impatiently.
