The door opened, Nataly got on with me just a bit behind. She taps the ticket machine with her card. "And I'd also like to pay for her. With my card." And she moves her hand back to the machine, ready to tap again. The driver swiftly blocks the machine with his hand and ask me "How old are you?". Well, 27, I say. The old dude apparently still only focused on getting back to the scheduled time asks again, because he did not hear. "Twenty seven, thank you!" I say louder, with a big smile and laugh. The dude laughs too, says something about how young I look and charges Nataly an adult bus fare for me.
