I don't question how someone else pronounces their own name, especially when lots of names aren't English names anyway. Just don't be a dick when someone else with the same name doesn't pronounce their name the same way you pronounce yours. Because I've seen people insist on pronouncing someone else's name the way they pronounce their own--because they're spelled the same way--even though the other person doesn't pronounce it that way. I think that's some bullshit.
