i got on the red line bart at civic center around 4:45pm on friday, 8/21. you were already seated, had your helmet on, and looked at me for a long moment. i had a big backpack on and walked to the back of the car to sit down. we both got off at north berkeley, smiled at each other, i thought i'd say something at the top of the stairs but i took a call and you disappeared. lmk what you remember of this if you want to grab coffee :)
