Not all the persons you know or all the persons you help or meet can be or are friends. People often call others friends just because they hang out together or because they're in the same class, at school. They'd probably need to choose more carefully which words to use.
As for me, I had friends, but they were all so busy when I needed any kind of support. Some of them acted in a cruel way after more than 10 years of "friendship". I can't call them friends anymore, or it could seem I'm a stupid. I don't care if they're gone and if they're no more with me, because I prefer to be left alone, than being with people who only think about you when they have favours to ask or when they have to solve their problems. I have really few friends, because now I choose them more carefully
