You may meet a person and instantly know that you will be best friends forever. Other friendships develop over an extended period of time. In some friendships you may feel a sense of equality, while in others there may be a clear sense that one is giving more to the friendship then the other. There are no rules about how a friendship has to be. If you are able to share your life with another human being, by all means go right ahead. All friendships are unique and special in their own way. Each one is valuable.
