For some reason the private DM suggestion made me think of a conversation I overhead some years ago at a resort restaurant in Costa Rica. We were scheduled to go out diving the next day, and at the next table our DM was conversing with a woman also scheduled to dive the next day. Part of the conversation went like this: Woman: "I have to tell you, I'm really nervous about diving tomorrow. I haven't been out in a really, really long time. Dive Master, shrugging: "That's okay. Neither have I." He managed to keep a straight face for about 2 seconds before breaking up, as did everybody within earshot. The self-described nervous diver stuck with him the next day and was just fine.
