Picture A and picture B have something in common:

they both show people spending their free time together.

In both pictures people look like married couples.

However, there are some differences between the pictures:

Young people in Picture A  are sitting on the sofa somewhere indoors (may be in their apartment)

while a couple in Picture B are sitting somewhere outdoors ( may be in the garden behind their house).

They are looking through the photos in their  photo album.

Another important difference is that the relationship between young people in picture A is getting worse at the moment.

(Neither of them are paying attention to each other) whereas elderly people in Picture B look like close friends. They like each other and having fun together.

An old lady is smiling when looking at her husband.

It is clear that young people  in picture A are not as happy in marriage as an old couple in Picture B.

As for me, I hope I’ll be happy in marriage as an old couple 

In picture B are.
