In the 21st century, friends are new family. Are there many extended families living together or at least close to each other? According to recent research people prefer change their location when they have their own families. Many people move from countrysides to towns, as well as they move from small towns to big cities. When you live in New York and your parents live in London it isn't easy to have a family get-together even on Christmas eve. However, all humans are presumed "social animals", so we need society to support us, to share our wins and losses. We all need someone to cheer us up, someone to spend the whole evening doing nothing, or, conversely, doing something really important. Also, we need someone to share common interests. There is a gap between our generation and the generation of our parents. The world around us changes so quickly, that it's becoming hard to keep on for elder people. Can you imagine talking about "Pokemon Go" game with your grandma? Or would you enjoy talking about knitting, gardening or whatever like that with her? Want it or not, we are completely different people, like aliens to each other. Thirty years ago, sixty years ago world wasn't so fast and running, people prefers live near their families to have someone close. In our days we need friends to be "on the same wave", to be understood and supported, and, of course, to understand and support, to share someone's interests too.
