The friends status that you choose will alert everyone that you are friends with someone, and that they are now part of your special circle of trusted people. The friend status lets you decide which friendships you make public, and which ones you keep to yourself, giving you the option to decide for yourself how much others know about the relationship.
Best friends make the good times better and the hard times easier.
I would rather walk with a friend in the dark, than alone in the light.
It's far better to be unhappy alone than unhappy with someone so far.
