How do you lie to your parents about a boyfriend?

It is more so on what you mean. If you are talking about not letting them know what kind of guy he is. Tell your boyfriend your parents have standards. Tell him some that would make them like him better (EX: Manners,Well-Dressing.) So then he can improve those areas in order to impress your parents. <-- That tip is a great one. It worked with all my boyfriends I had in High School. But if you are talking about not letting them know you have a boyfriend then keep it a secret. Say your just friends. Which really isnt lying because you have to go passed the friend stage to get there to MORE then a friend stage. You can say there is not romantic emotions between you two. If you are talking about something else combine these tips. It works like a miracle. Good luck.
