1. Your family is always there for you. They always care about you and love you. Why do we have friends then? Being a friend teaches people important social skills, develops character and bring fun and joy (pantocms). People who have friends are happier and live longer. 2 Children start making friends when they start kindergarten (metoda can), usually at the age of 3 or 4. At this age, friendship is all about playing together and having fun. Children easily make new friendships and forget the old ones. They don't usually understand that other children can do things in a different way, and they often say, "You're not my friend today Even so (tem He menee), children need to have friends and learn how to share and listen 3. Teens spend less time with their families and more time with a friend or a circle of friends. Friends play a huge role in a teenager's life, so it is very important to choose friends who are honest. In a friendship, teens practise social skills such as communication, negotiation ( Germe Договариваться) and problem solving. Friends help a teenager develop their own understanding of life and start building their identity (индивидуальность). 4. Adulthood is when people are the strongest and the most independent in their lives. Adults support themselves and their families: children and their own parents who have become old Adults have a job and can have all they need. Do adults need friends? Of course, they do! Adults, too, sometimes need help or advice. They need someone who shares their interests and accepts (DPWH Maer) them the way they are. 5. People can make friends at any age and keep them for many a years, sometimes for life. Having a friend when you become older is very important. Older people usually do not work, and they often live alone because their children have grown up and left home. This can make a person feel very lonely (OANHOKO). How can you help your grandparents feel happier? Visit them regularly and call them more often! How can you help an old man or woman who live next door feel happier? Make friends with them! Old people don't need presents. They need to be needed.
