Only Child

You've got just one egg
You're not going to make an omelette
Flying just one way
You're not going to make a jet set

Sister, brother, wherefore are thou?
No need for bunk beds in my bedroom, now

Oh, damn you, dads
Why did you settle for only me?
I'm an only child
More than enough for them, but not enough for me

Only child, only child, only child

The only berry on my family tree
