I wanted to be with you alone

And talk about the weather

But traditions I can trace against the child in your face

Won't escape my attention

You keep your distance via the system of touch

And gentle persuasion

I'm lost in admiration, could I need you this much?

Oh, you're wasting my time

You're just, just, just wasting time

Something happens and I'm head over heels

I never find out until I'm head over heels

Something happens and I'm head over heels

Ah, don't take my heart, don't break my heart

Don't, don't, don't throw it away
