Analysis of Heart Shaped Key

When we first met, it was not love at first sight
You were a woman - I've seen those before
And I was a boy trying my best to be a man
We went among our business without hesitation

But as the days past, you crept into my mind
You were there when I first woke up; it made me smile
What was the exact time you bypassed my walls I pondered?
But I quickly gave up; as there was no point in fighting

The reason I felt this way, the reason why I was still alone
I was waiting for someone like you, someone who was a complete unknown
Because you helped me discover the key to my heart
It was because you made me laugh
