You should have nothing to fear from your family and friends, but to know your enemies, where they are and what they are capable of is by far better then being surprised in the dark...You don't have to be friends with the enemy to know their capablities.
The old saying of "keep your friends close and your enemies closer" sounds about right.
Keeping close to your Enemy Means: You need to do everything to keep tabs on your enemy so you would know where they are at. So if they do try to attack you then you have been prepared and can hopefully even turn it to your favor.

Machivelli says that in The Prince.
We should keep our friends close because they encourage us to always keep moving ahead whereas we should keep our enemies closer as they keep telling us about our weaknesses and faults which enable us to correct them and not repeat them again.
