When a person requested to become Hazrat's disciple one of the first advices hazrat gave him was, "Maintain the same kind of relationship with your friends as you have always had. They should not feel that you have become too dry, or too rigid, or that you don't talk about anything except that one topic (religion). However, if there is an occasion when they are engaging in something which is a sin then get away from them and do not care who gets upset."
