"Don't you know what that is? It's spring fever. That is what the name of it is. And when you've got it, you want--oh, you don't quite know what it is you DO want, but it just fairly makes your heart ache, you want it so! It seems to you that mainly what you want is to get away; get away from the same old tedious things you're so used to seeing and so tired of, and set something new. That is the idea; you want to go and be a wanderer; you want to go wandering far away to strange countries where everything is mysterious and wonderful and romantic. And if you can't do that, you'll put up with considerable less; you'll go anywhere you CAN go, just so as to get away, and be thankful of the chance, too."
--Tom Sawyer, Detective, "An Invitation for Tom and Huck" by Mark Twain
