Choosing the wrong friends may subject you to unrealistic life expectations which will result in conflicts in your family. Keeping bad company might result in one becoming bad too. There is a saying which says "show me your friend and I will tell you who you are".
If a person keeps bad friends, there is a high possibility of the person becoming bad. A family always wants the best for its members, so, if you keep bad friends, you'll most likely have conflicts with your family because they'll be scared of you getting bad.
The family will try as much as possible to separate you from the bad friend which will cause a lot of misunderstanding if you don't listen to them.
