For someone who likes travel as much as I do, it is difficult for me to convey how much I hate talking to other travelers.
They end up falling into one of two categories: the people who have unlimited money and want you to know how many Exotic Trips they've made and the people who want you to know that they may or may not have lots of money but they do all their travel out of a backpack without a dollar in their pocket.
When I get roped into conversations or find myself in enclosed spaces in which I have to overhear them I always choke back the urge to yell questions at people when they're regaling their audience with tales of the absolute BEST time to go to Montserrat or how this may be nice but you just HAVE to see Angkor Wat or the time they were backpacking through Uzbekistan and a roving band of nomads gave them a lift on horseback.
What was it that you liked about it? Why did you pick that place to travel to? What did you do there that you couldn't have done somewhere else?
Yeah, I know, we all have the Tourist Gaze and there's nothing you can do to avoid being a traveler while you're being a traveler. It's amazing, though, how predictable are the lists of destinations people rattle off when they start playing this game of tourism oneupsmanship. Tell me about someplace you've been that isn't straight out of the condensed list of Vacation Bucket Lists by Conde Nast and I promise I'll be a rapt audience for as long as you want. Yeah, we all know that Prague is awesome, that's why everybody and their goddamn brother has been to Prague a dozen times because they Google "hip vacation destinations" and Prague comes up on every list (full disclosure: Some day I would like to go to Prague).
But I really like interacting with people and their experiences more if they're telling me something I can't find in every magazine on the rack and can say something more interesting than "Man, it's SO awesome" to describe the experience. Tell me about the Museum of Bunions, if for no reason other than to prove that you have some interests and aren't simply trying to check a bunch of popular Travel Things off a list without any real motivation beyond being able to afford it and wanting to tell people you did it.
tl;dr: people are boring and an old man is cranky.
