True Friend

I hear a lot from friends of mine
That true friends are hard to find
That true friends are those
Who will come when you call,
When you're needing a sign
A sign that they are there for you
They'll come when called, they are true
These are they who come even when
You do not call, but still they can see you fend
You fend off those who try to attack you
Those devils small, but many, true
So who is your friend and who is not?
You'll find out when your trial is wrought
You will know, for they will catch you
When you fall, they're there too
To catch you, help you in this your time of need
They always will, that's who they are indeed
