I should have known
When we first met
I should have known

Checked his clothes
Been like Sherlock Holmes
I should have known
I should have known

When he bookmarked her page
I should have known

Oh, I should have known
He said it was me who was deranged

I should have looked through his phone
Checked his clothes
Been like Sherlock Holmes
I should have known
Oh, baby, I should have known

He said he was out with his mates
Oh, I should have known

Yes, I should have known it
That she’d be there on a plate

I should have known
I should have looked through his phone
I should have checked his clothes
And been like Sherlock Holmes
I should have known
Hmm, hmm I should have known

And, I should have known
That he’d be blind by the blues
I should know

Yeah, I should have known
He’d think that he’d have nothing to lose
I should have known, oh yes

I should have known
I should have looked through his phone
Checked his clothes
Been like Sherlock Holmes
I should have known
Oh, yeah, I should have known
