It probably helps that it has been a very short amount of time since I was a student, so I remember what it is like. As a student, any time you get doing interactive learning of practical skills feels immensely valuable and helps keep you interested.
Also, there are no "gunners" in the group of students who are on my ward, although they are all generally enthusiastic, so it is fun to tell them what I know and try to get them to start learning practical skills.
Nobody has followed me into the bathroom yet, so all is well with the world. I guess that since I'm not the one marking them, they don't feel the need to impress me with their keenness at every opportunity.
This results in a level of interaction where they are with me for only short periods of time, and are doing other things most of the time, allowing for brief and enthusiastic interactions where I don't get tired of them, and they don't completely exhaust my limited pool of knowledge. Fun times.
