Why?

Nothing special about this, but it's relevant to my everyday life.

I've always wondered to myself
if I'll come back as something else,
and how many lives I might have had,
will I go to hell if I am bad?
Is god a she and can she see,
all the things that happen to me?
Can she see me in the shower?
Will I be judged in my last hour?
Are angels here beside me now?
How many sins will god allow?
I could think my life away,
just wondering why I'm here today;
but just one thing I need to know,
one thing to ask before I go,
just one more thing to ease my mind,
why the fuck is my train never on time?
