A little bit of what you fancy

I’m unsure about this.

Not only that, but I’m unsure about what, exactly, I am unsure about.

I can, however, categorically state that at 3.39am, one really ought to be spark out, preferably in close proximity to the person you’d most like to be in close proximity to, so that should one, for some unknown reason, rise from one’s slumber (did someone mention a ginger cat?), it will be beside a warm body, breathing gently into the night air, seeding it with their fragrance.

How much space is it really necessary to leave between these lines?
