(01) Strangers. Are people you do not know. Turn them into acquaintances.
(02) Acquaintances. Are half-way friends. Half friend/stranger. Turn them into Friends.
(03) Friends. Are people you know very well. Keep them as friends.
Make Your Husband/Wife Your best closest Friend. Because Your life depends on it. Because S/He is the always 5 steps near You to help/kill you.
If it is Your blood Father/Mother. They must always be Your first Friends. Because They love You.
All those Friends who are able to teach You things are Your Zen Masters Teachers. Chinese Saying: "one day Teacher. Forever a Father."
You need Friends to survive in this world.
