A Familiar Sentence?

I am in the middle of John Green's 'The Fault In Our Stars'. And perhaps it is because I am unable to sleep anymore, exahusted all day, wide awake as soon as my head hits the pillow, then ready for a deep sleep as soon as the day begins...but I was struck by this  line:

As he read, I fell in love the way you fall asleep: slowly, and then all at once.

Personally, I think that is a beautiful line, perfect for its simplicity.

But when I told Tyler, he thought it sounded cliche, a line he's heard a million times before.

Perhaps the simplicity of the sentence makes it feel familiar?

But I really don't believe I've ever heard love described that way. 

What do you think?
