Oh it's not that - it's just as a Brit I reserve the right to roll my eyes at anyone who isn't a Brit
*chortle*
I have dual nationality - British and Irish - what you gonna do, roll one eye? 
I have a British passport but can also hold an Irish or a Polish one. [unless they changed the rules since I last checked] .
that's a lot of eye rolling I think 
And just in case anyone wonders why you'd want more than one passport... if one was travelling all over the world as some of my mates managed to do years ago [to any Americans that's those places on the rest of that round ball we live on and not just America 
] It is handy to have different passports to enter certain countries as some will refuse entry if you have a stamp from another country that they don't like.
