It was a moonlit night
Their eyes met from across the floor
The moment took her by surprise
She'd never really noticed him before
And they began to talk
A crazy notion came into their heads
So hand in hand they went out "for a walk"
Only to find her daughter wide away, wanting to sleep in mommy's bed

Leave grown-ups alone
If you want to be a sister or a brother
Leave grown-ups alone
They need some time with just one another
Mind your own business until they're through
I guarantee you'll see a smile
'Cause you gotta leave grown-ups alone
Once in a while

The girl was three years old
And in her own way so very much alone
She wanted more than anything
A baby sister or brother of her own
And she would beg her mom for one
At literally any chance she'd get
But when her mom wanted some time with her "special friend"
That little girl would scream and cry and throw a fit

Leave grown-ups alone
If you want to be a sister or a brother
Leave grown-ups alone
They need some time with just one another
Mind your own business until they're through
I guarantee you'll see a smile
'Cause you gotta leave grown-ups alone
Once in a while

Ooooooo, ooooooo
Oh oh oh
Sometimes grown-ups say
Ooooooo, ooooooo
Oh oh oh
You gotta leave 'em alone when they say
Ooooooo, ooooohhhhh
Ooooooh, ooooohhhhh
Oh, you gotta leave them alone

The boy was just fifteen
And already considered himself a man
And he'd managed to catch the eye
Of one of his little sister's little friends
And those two would try
To find a quiet place to sneak away
But it seemed that everywhere they went
His sister and her gang
Would show up and demand their friend come play

Never leave teens alone
Or you're gonna become an uncle or an aunt
Never leave teens alone
When they keep trying to touch each other's pants
Just get in their business even if they're upset
They'll thank you eventually
'Cause you can't leave teens alone
Ever
