feel the need to go on about how hot it is where they live compared to Britain.
It's like stating the obvious, I feel like saying, you moved to Dubai of course it's hotter than the UK which is covered in snow. But so many Ex pats seem to feel the need to almost brag about the bloody hot weather when the move. Yawn!
Disclaimer: I have lived in hot countries for part of my childhood and again as an adult so I know the pros and cons of living in the sun and so am not remotely jealous.
