As if I'd never noticed the way she brushed her hair from the far end.

The story:

I listened to the song a million times and had a mental picture of a girl with a hairbrush, brushing her hair starting at the far end and going toward her head. Of course you would notice a person brushing their hair in such an unusual way. I finally heard it one day by myself and just felt stupid. My wife thought the same thing before, so either it really sounds like that or I sang along and she never caught it.
