Women, if you're cheating on your husband with a married man, take charge and make sure you help him cover his tracks. He doesn't have the knack for sneakiness that you do.
Also, on a related note, if you're both thinking about leaving the person you're with to be with the person who you're cheating with... you're idiots.
