Just that really - I am Irish and have been living in Scotland for a few years, and it has happened repeatedly. I am never quite sure what to say as it is always a flippant casual remark (e.g. In work someone often says a certain system is a bit Irish) but I find it weird given I am obviously Irish. I have sometimes said back that maybe they should think about what they are saying, given that I am Irish myself, but I seem to be viewed as hyper-sensitive.
Any ideas of a good come-back as I am useless at these things?!
