2nd floor: Delivery man walks out. As soon as the lift doors close I feel a pair of arms wrap around me tight from behind. You squeeze tighter; my heart soars higher.
3rd floor: The lift doors open. I attempt to take a step forward - "No, don't go." You don't loosen your hold. And we stay like that for a few seconds longer while the door stays open.
(And I wonder if I ever cross your mind / For me it happens all the time)
