I chose this quote because I think that it says a lot about what the prince and the pauper both expected to happen when they traded places. The prince thought that he was going to have this wonderful experience being able to do whatever he wanted without having to be royalty anymore but still being recognized as the prince. However, he soon realizes that since the people no longer see him as the prince, the is treated with no respect and pushed out of the way. The pauper thinks that he will be able to live his dream of becoming royalty and that he will enjoy this life more than the life that he had before. But once he is in the position of royalty, it is much different than how he had imagined it. Especially since no one can tell the difference between the two boys.
They both end up in positions that they don't enjoy being in, and I think that this quote sets up the rest of the book in the sense that both boys are no longer in their niches. Neither one of them has been treated the way they are now treated and Twain seems to poke fun at the fact that sometimes when we get what we want, we realize that we don't really want it anymore.
