Объяснение:

The photo shows three older women who are sitting on a bench in a park. I 1 can’t be sure, but I’d say that they are all friends. They are dressed in light coats and are wearing headscarves and there are lots of leaves around the bench so I’m pretty 2 sure that it’s a cool, autumn day. It 3 looks as if two of the women have moved closer together to look at something that is in the middle woman’s hand. It’s 4 hard to say, but I think it’s a mobile phone. It’s 5 clear that the two women find something really funny because they are both laughing. Not 6 only that, one of the women is using a tissue to wipe a tear from her eye. It 7 could be that they’ve just seen a funny photograph or read an amusing message. The third woman is sitting further along at the end of the bench and can’t see what they’re looking at. Judging by her 8 expression, I’d 9 say that she feels quite annoyed. 10 I’m certain that the other women have completely forgotten about their friend and wouldn’t even realise if she got up and left them.
