When I look at old stuff, lookin' like it's over

Lookin' like I'm never going to be that again

Crying over old loves even though they're over

Never gonna stay friends, yeah, stay friends.

They think I'm happy

They think I'm happy when I'm sad

They think I'm happy

They think I'm happy when I'm

They think I'm happy

They think I'm happy when I'm sad

They think I'm happy

They think I'm happy when I'm.

Can't look how we made it, say "congratulations"

Lookin' like I'll never be lonely again

See me in the mirror, nothin' ever changes

Never see the sunset, only in my head.

They think I'm happy

They think I'm happy when I'm sad

They think I'm happy

They think I'm happy when I'm

They think I'm happy

They think I'm happy when I'm sad

They think I'm happy

They think I'm happy when I'm.

Never gonna stop, never gonna calm down

Never gonna stop

They think I'm happy when I'm

Never gonna stop, never gonna calm down

Never gonna stop, no

They think I'm happy when I'm.

I put on a smile, don't need a face-lift

Why can I when everybody fakes it?

Well, they think I'm happy

Like they know exactly how I feel

You ain't real, but they still think.

They think I'm happy

They think I'm happy when I'm sad

They think I'm happy

They think I'm happy when I'm

They think I'm happy

They think I'm happy when I'm sad

They think I'm happy

They think I'm happy when I'm.

Never gonna stop (I try), never gonna calm down

Never gonna stop

They think I'm happy when I'm

Never gonna stop, never gonna calm down

Never gonna stop, no

They think I'm happy when I'm.
