regarding PG

I know I could've done much better,
Wish I'd always been around.
Hope you're able to forgive me later
For the times I let you down.
Oh mother, what can you do?
There's no denyin'
They're growin' up in front of you
And they ain't even tryin'.
Funny how some things are different
But others are the same.
Now you've got your own opinions,
And your interests changed.
Oh mother, what can you do
When there's no denyin'
They're growin ' up in front of you
And they ain't even tryin'
Oh mother, what can you do?
There's no denyin'
They're growin' up in front of you.
