To live fast and die old
What a perfect work of art
To live with someone you love
And both get in bed before it's dark
Life gets better, the hangovers get worse
Oh, when did I get so old?
I even pay train fares now
And most days, I do what I'm told

I wake up every morning with someone I truly love
And every day, I act more like my mum

REFRÉN

I watch what I eat
I stay in and watch films
Man, I have to pay my bills
I must be grown up
I'm working on my house
I'm building a career
How on earth did I get here?
I must be grown up

I'm still someone's kid
But I want to have my own
I have less friends but more best friends
And they're scattered around the globe
I think about getting fit
Like investing in my health
And then I think of something else
Like eating a pizza by myself

I wake up every morning with someone I truly love
And it's scary how much I love my dog

REFRÉN

I watch what I eat
I stay in and watch films
Man, I have to pay my bills
I must be grown up
I'm working on my house
I'm building a career
How on earth did I get here?
I must be grown up

Woah, woah
Woah, woah
Woah, woah
Grown up
Woah, woah
Woah, woah
Woah, woah
Grown up

We all miss school
And most of us are married now
Some people break their vows
It's kinda weird how it all works out
It's strange to know there's faces
That I'll never see again
Losing family, losing friends
Each one is worse than the next

I wake up every morning with someone I truly love
And the thought of losing them just cuts me up

How on earth did I get here?
