I am on a flight from London to Lisbon, and because I find it annoying to pay extra money to secure an aisle or window seat, I am in the middle. Thanks RyanAir, but that's not the point. On the window side of me is a Portuguese young woman, we will call her R for the purposes of this thread. I realise just after sitting down that I have not done DuoLingo today, so knowing we have some time left of boarding, I open the app and start the lesson (turning off listening and speaking.)

Wow. That sounds exhausting 🥴
