I was confused by the way you moved
So casually yet so guarded
So cold yet so warm

You got me so nervous I was left strickened and weakened.

I thought you seemed so different
But others still perceive you the same

Perhaps

I just never knew you.

Explanation: Have you ever met someone you haven't seen for long? Someone you once shared a kiss with? I've always thought I knew him, at least a little bit. I think we've both changed, or maybe, we just never knew each other.
