No, I've never seen him bored. But he is a male so I don't think he has much interest in his nails. But really, sometimes I'm surprised how focused he is, he doesn't miss any of my body language, he never looks at his phone or a computer, only time he might look away is to occasionally write notes. It's almost scary how I can't hide anything from him, but yes, it would bother me a lot if I thought he was bored, or look absent, especially if that was happening often. Not sure if I would be able to address it, knowing myself I would probably just stopped going. But if i otherwise liked them I would maybe try to find a way to talk about it. Sometimes they don't realize how things they do can affect us
