you know they're your true friends when they call, email, msg, and try to contact you by all means because they sense something is wrong.
you know they're your true friends when they care about you and keep their calls open 24/7 for you until you are ready to talk.
you know they're your true friends when they worry even if it is something small.
you know they're your true friends when they understand you without having to talk to you for a while, but still know something is off.

you know they're your true friends because they know you without you telling them.

thanks for being a friend.
sorry i didn't pick up, reply, and went 'missing' for a few days...needed some alone time.

it's through these times you find out who really cares.
