Mr.Suicide

I have a friend who's always there
When no one else is left to care
& when comes the inevitable
I know his ways are creditable
For in him I do trust
& for him I do lust
So when my world comes crashing down
And all my friends have departed town
There will be only one person left
To see me through until my death
& in his rules I shall abide
I shall succumb to Mr. Suicide.
