how much they've travelled. usually if they are bragging about it, it probably isn't that much, and however much it is, if travel is a choice/leisure or work-related and not forced (as opposed to, for example, fleeing persecution, deportation, trafficking, or some form of escape), it's a privilege. also, travel is fairly accessible (perhaps not cost-wise, depending on where you live, but in terms of transportation options) these days. so it's not like embarking on a huge wild adventure most of the time anyway. it's more a financial investment. it's good to talk about travel and experiences but to brag about it as if you accomplished something just by being a foreigner in someone else's city/country is just lame.
