Yes! Exactly! I was going to make a quip about that type of introvert friendship, actually. The difficulty being that they like and respect each other so much they never talk. Big parallel play/reading in the same room vibes.

Even if it's easy mode, Linhardt thinks it's impressive and has a lot of questions. Which he's more than happy to ask via written notes if talking in person is too much. Because sometimes it is. And talking is so much easier in text format...
