I was thinking that if I ever get the chance to choose a flatmate, I would definitely choose someone from overseas than choose someone from the local populace.
Local people are to me uncultured, demanding, inpatient and arrogant. Whereas people from overseas are having overseas experience (possible not the first time). Having learnt from other cultures their eyes are open to different perspectives. If you tell them something, they will stop and think about it before agreeing disagreeing or having no opinion to the matter.
People from overseas also have a high chance of speaking another language. Not only do they learn something from your culture, but you get to learn something from theirs. You can swap languages, music and probably most importantly, food.
Next time you get to choose a flatmate, choose the one with the cute accent.
