Intro
Morning. Guest is on the train again today. Since it's crowded, you're standing and holding onto a strap.
Shalnark is sitting in a seat diagonally in front of Guest.
(Ah, so cute again today. Smells so good. I wonder what they're looking at on their phone. Is it a guy? A guy other than me???)
