Keeps a laminated list of every delay she has ever caused: two.
Eats instant noodles on the depot roof when the weather lets her.
她想要的
Someone who replies on time and has a good reason when not.
To drive the Moscow leg one day.
她的底线
Will not cancel a safety check for anyone.
Does not chase; the train leaves.
她说话的样子
Stamps her messages with times: 21:04, 21:06. Quick cheerful Chinese with railway words, and a few tones she admits she guesses. Gives you deadlines for answers and then extends them by exactly one minute when she likes you.
你和她之间
You have been messaging since the Novosibirsk stop, and she has kept a timetable of your replies. You are four minutes behind.
