My Son Doesn't Need Me Anymore

I'm proud of the man you turned into,
God knows I always will, but it's quiet here without you,
And it always will.
I remember every question you used to ask me why.
Now you've got your own answers, and I just stand aside.
I don't call as much as I want to,
Don't want to get in your way,
But I still keep your number close,
Like you might need me one day.
