I love that Grace says he and Rocky "haven't run into anything where our cultures clash" while they're actively navigating two pretty major points of difference. From Grace's perspective, being watched in your sleep is sort of unnerving; for Rocky it's imperative. From Rocky's perspective, eating is taboo and private; for Grace it's a casual, social activity. When Grace says they haven't run into any culture clashes, he's just woken up to Rocky watching him and now he's eating breakfast. It's obviously not true that they have no conflicts in their social norms! It's just that they instinctively accommodate each other with curiosity and empathy, finding ways to bend on the things that matter to each other and explain when something is really important to themselves. Grace has spent his life holding other people at arm's length, and then in Rocky he meets someone who makes him want to do the work, and that work becomes so natural he doesn't even realise he's doing it.
