1. Social media
(However, with the explosion of social media since then, many people now have over 300 people who they think of as friends.)
2. Different backgrounds
( This means that we have more chances to meet and make friends with people from different cultures and different backgrounds.)
3. Less security
( People now have less security at work and this also means that they find it harder to build new relationships.)
4. Convenience
(Young children often choose their friends because of convenience, for example, they go to the same school, they live near each other or their parents are friends.)
5. Mental health problems
(People who spend time with friends have fewer mental health problems and are generally happier and in a better physical state of health than people who spend their free time alone.)
