But we would feel lonely if we never had a friend. No two people are 4 . Friends sometimes don't get on well. That doesn't mean 5 they no longer like each other. Most of the time they will make up (言归于好), and become 6 again. Sometimes friends move away. Then we feel very 7 . We miss them very much, but we can 8 them and write to them. It could be possible that we could even see them again. And we can also 9 new friends. There's more good news for people who have friends. They live longer than people who don't have. Why? It could be that they are 10 . Being happy helps you stay well and it could be good just knowing that someone cares about you.
