A guy that can make you laugh in times of heartache, times of depression or embarrassment, sadness or despair, or even just a regular day, is a guy that will help nurture a healthy relationship. Not that he has to be a jokester all the time, or a class clown per se, but a guy that can make light of the situations that might be difficult for you can surely make you feel a lot better. Laughter is a powerful medicine after all.
