OOC: Sigh. You wanna name this one, or shall I? :p
Um--no?
In my approach to play, incidental characters don't get names unless they cease to be incidental. For the moment, this guy's name is "the driver"; probably in future his name will be "the driver of the carriage through Sherwood Forest". That's a name I will have little trouble remembering.
If you want to call him something else, you certainly may call him anything you like; but when you want me to know who you mean by that, you will have to add "the driver" so I know.
There are a lot of tricks like this, and some of them can be a bit silly. For example, anyone who played in E. R. Jones' games knew that the stableboy's name was "Bob", even if it was the thousandth stableboy, and anyone you met whose name was Henry was a professional thief. Players used to tease that, as their characters would walk into unfamiliar towns and address the stableboy by name immediately, and tell the barkeeper they were looking for someone named Henry.
I avoid that. I said "He tells you his name". Now your character knows his name, and I know that your character knows it, and you will use it. If you want to make a point of using it, you can say something like, "'So you see,' and I address him by name, 'it comes down to this.'"
Otherwise next week at this time, the driver will be a forgotten character and I'll have burned up a useful name.
Does that make sense?
"Beg your pardon, Father; I did not recognize you as a holy man in your traveling attire."
"What, Nottingham? Well, it's not London, you understand; it's not even Canterbury. But it is the biggest city in these northern parts. I don't think the crown takes it too seriously--the shire reeve is really the highest ranking nobleman in the city, charged with protection of the forest, which is more than he can handle to be sure. There are a few other nobles who stay for extended visits, as they enjoy the hunting--but that's not so common as once way, or so they say, since this Hood and his thugs have made the forest unsafe for them as has the divine right of kings on them."
