The question "What is friendship for you?" has got a lot of answers. For me, friendship is when you have 1 real friend, who understands you, who can help you, and who will never betray you. You can have thousands of friends, but the chance that they won't support you in a hard situation is almost 100%. No, I don't want to say that a lot of friends are bad. Sometimes it's good to contact other people, but you must have at least one "soul mate".
