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
