She doesn't say anything; she doesn't need to.
In spite of everything going on, the hustle and bustle of the world outside, when you're with her it's like everything screeches to a halt. You can just...be together, doing everything or nothing.
You stare, and she stares right back, relishing your addiction to her. You both know what comes next, but you don't want the quiet anticipation to end, either.
