I picked you up from school today

Should have seen the look on your face

Said you were an astronautAnd just went to the moon

And next week you′ll be flying planes

As Spider-Man to save the day

You don't know your dreams will change, but I do

And I know your first sip of mom′s rum

Won't be when you turn 21

And not every friend that you meet at 15

Will be there at 50, and I know

The world can be quite scary

Make you feel so ordinary

Tell you who you'll be before you′re six

You′re gonna have to fall a few times

Before you finally hit your stride

Hope you don't forget to take a risk

′Cause you're just a kid

Dropped you off at school today

Wish you′d see the look on your face

Didn't want your friends to see

Your sister, you′re too cool

You're 16 now and you're doing fine

School sucks, but you′ll be alright

Got nothing figured out, ah, no

And I know you′re gonna feel heartbreak

You're gonna have lots of bad days

Some of your friends will be fake and two-faced

It′s too much to take in, and I know

The world can be quite scary

Make you feel so ordinary

Tell you who you'll be before you′re six

You're gonna have to fall a few times

Before you finally hit your stride

Hope you don′t forget to take a risk

'Cause you're just a kid

Time goes by a little quicker

I′ll always be your big sister

Love you to the moon and back

And this, Austin, I promise
