"Dogs In Our Twenties" lyrics

Dogs in our twenties
They don't miss a thing
Boxes up the staircase
Mattress on the floor
Dreaming out the window
Waiting by the door

Dogs in our twenties
Don't always get a yard
They put up with the first time
Figuring it out
Every little mistake
Every different town

Always there for all the long nights and the tears
All the change and wild and crazy in those years

All you ever wanted was love
All I ever wanted was more time
Even when we didn't have much
You stayed by my side
We grow up together
I don't know why
Dogs in our twenties can't live our whole lives

Dogs in our twenties
Help you pick your friends
The good ones and the bad ones
They can always tell
Know you even better
Than you know yourself

Dogs in our twenties
They teach you how to trust
They teach you that forgiveness
Takes a little work
And when you gotta let go, they teach you how to hurt

All you ever wanted was love
All I ever wanted was more time
Even when we didn't have much
You stayed by my side
We grow up together
I don't know why
Dogs in our twenties can't live our whole lives

Oh, I just wanna thank you for the years you had my back
You were the best friend I ever had

All you ever wanted was love
All I ever wanted was more time
Even when we didn't have much
You stayed by my side
We grow up together
I don't know why
Dogs in our twenties can't live our whole lives

Why can't dogs in our twenties live our whole lives?
