I'm so confused right now... 
Why hello, Brandon? Are you Brandon? Yes, I'm Brandon; are you Brandon too? Why, yes. Well, I'm glad that's settled. ... ... Hey, Brandon, it's Brendan!! GAAAAAAAAAAAAAARRGHBLARGL--
Oh, that rascally Brendan, always showing up to throw a monkey wrench into things... 
Thing is... every time I tell someone in Ireland that my name is "Brandon"... they repeat it back to me... and 95% of the time, they repeat it back to me as "Brendan".

It's like, "Great, thanks... I know how to pronounce my own name... hell, I know more about the vagaries of vowels than you probably ever will or will care to... so when I said BrAndUHn, I didn't mean to say Brin-den or Brendan" (without invoking IPA, I can't be more specific than that... I could do that... but I don't feel like going to the effort

) (I have been this frustrated with someone in real life before... b/c it took like 5 minutes of repeating the two names back and forth for them to cop on... and my ultimately having to explain it to to them

)
