No, not a joke, not really. Actually, it's all because I don't want to become one - Dr Colon might as well be a cartoon character.
You should be proud of your polish heritage.
As far as being proud of my heritage comes, well, maybe it's just not this stage in my life yet :P
Your name is part of who you are
I am not really ashamed of where I come from, besides it's not like I'll ever pass for an English person with my accent. My identity is more than just a name, so I don't really feel like I am going to be compromising a large part of it.
It's not the question of people mispronouncing or misspelling my name either. I am just afraid that when I will start my foundation year next year, I am going to be Dr What's-his-name and in the competitive environment it's always going to be easier for the nurse to call Dr Gray, Dr Stevens or Dr O'Malley than me.
Also, I don't have problems forcing people to get my name right in social situations, but we're talking about my patients here, I am kind of there for them, not the other way round.
