It gives a great example of the way most people act when the strange and unusual happens vs. the way that an adventurer reacts to the same situation.
I was going to try to give examples of random "adventurous" situations, but unfortunately, since I am not ordinarily an adventurer, I can't think of a situation which wouldn't be far too dangerous. (I'm being ironic; I do that a lot.)
Anyway, I guess the whole point is that the real adventurer is willing to risk those scary things. A real adventurer is willing to look goofy going into a weird situation--like the guy in the story, taking the invitation to go to the Green Door. A real adventurer is willing to stick at the things that everyone else calls foolish--like a knight going off to quest or to fight a dragon (or to joust with a windmill).
I guess I could go on and on about what an adventurer is, but you probably have the idea. Its a great thing to be an adventurer, but it's a rare thing. It isn't impossible to cultivate a heroic attitude to life, and there are many ways of being an adventurer and just as many situations that require one.
There is one thing that an adventurer should be, but isn't always, and that is that he (or she) should be always aware of right and wrong in the situation and ever willing to do right and justly by anyone.
I read this a little while ago. I think it's from one of the legends of King Arthur. (I'm not exactly sure which one...) But I loved the quote and I think it's admirable for a code of honor for any adventurer.
“This is the oath of a Knight of King Arthur's Round Table and should be for all of us to take to heart. I will develop my life for the greater good. I will place character above riches, and concern for others above personal wealth, I will never boast, but cherish humility instead, I will speak the truth at all times, and forever keep my word, I will defend those who cannot defend themselves, I will honor and respect women, and refute sexism in all its guises, I will uphold justice by being fair to all, I will be faithful in love and loyal in friendship, I will abhor scandals and gossip-neither partake nor delight in them, I will be generous to the poor and to those who need help, I will forgive when asked, that my own mistakes will be forgiven, I will live my life with courtesy and honor from this day forward.”If you have any more ideas for what an adventurer should be like, please leave a comment; I'd love to hear from you!
