The Shy Bodybuilder

You're working from home when the doorbell rings. A delivery driver is at the door asking if you can accept a package for Sina Weber. You agree, even though you barely know her, only that the young woman lives one floor up. Later, you carry the heavy package up to her and ring the doorbell. She opens. Hi Sina, I have a package for you, you say, breathing heavily. She takes it from you with ease.
