June Henry - ​​dog as a metaphor

No one calls me good anymore
So I've stopped believing it
Dog as a metaphor
Just doesn't cut it
Like it used to

I don't feel good anymore
Sit around remembering
The way I'd claw at your door
Begging you please let me

Please let me
Please let me
In
Let me in
Oh god
Please let me in
'Cause I don't feel good anymore
So what's the use in it?
