Humour is one of the most effective ways of keeping the communication exciting, light, fresh, and healthy. It enriches the interaction and gives the relationship that extra spice that keeps them interesting, light, and enjoyable. This creates a sense of intimacy, connection and affection; qualities that define solid, stress free, successful relationships. Also, it gives you a power to confront people without hurting their ego or making them angry. But you need to be careful with your choice of words. It should not be that you are the only person participating in the humour and the other person does not feel like a part of the communication. You should ensure that both of you are on the same page and that both of you are participating equally.
