In the picture number 1 we can see a group of young people. May be they are students nad they are walking after university. They are staying on the street. The wheather is really good so they just having fun and enjoying their lifes.

In the second picture we can see a family. They have a picnic in the park. I think it is summer there and they have gone outsite to get some fresh air. They are having fun with each other. I can say that this picture shows to us what is the real cheerful life.
