What are the universal ground rules for having/being a friend?

Question

I worry about that since it involves more than "enjoying somebody's company"....a person can be roped into cults/gangs/etc. just by offering that which masquerades as "friendship"-

- One rule could be, "you value your friend's individuality", which neutralizes "you require your -friend- to "do what me & my buddies do" type thing....

Answer 1

Honesty, treating them the way u'd wanna b treated, and never tell  secrets.

                              

Answer 2

the ground rule of being a friend is to be honesty with them no matter what.

Answer 3

The Golden Rule - treat people the way you would want to be treated.
