Twenty years ago families used to have 2-3 generations. Frequently fellows didn't know their grandparents. But according to the latest researches families will consist of 3 or even 4 generations. Here are some predictions:
1) People will live longer and, as a consequence, (will) know even their grand grandparents
2) Families won't have a lot of children. As a result, children won't have cousins
3) Children will grow isolated from other ones, and that will make them selfish
4) Couples will divorce and marry, so many children will get stepmother or stepfather
5) There will be a lot of children, which marry and return to theirs families
6) There will be more single-parent families

Saturday is a perfect day for her. It starts at 9 o' clock with a big breakfast. Then, she puts on her special uniform and she sets off with her best friend, Christina for the Scout Club! There, they meet up with the Scout leader and the rest of the team and they go camping. Later, they arrive at the forest and put up their tents. After that, the leader teaches them new things, like how to tie knots and build fires. In the afternoon, they play football or go climbing. At 6.00 o’ clock, they cook dinner on the campfire. When they finish dinner, they go to their tents. They tell stories before they go to sleep! She absolutely loves Saturdays!
