its not disgusting to live with the same group rather than others. maybe for others its OK! especially for westerners and other european peoples. they are kind OK! but sometimes Arrogant people because they felt really superiors if they in front of other 3rd World people. thats why Filipinos and Indians like to find same as them. so that after a long tiring day in work which by the way you mingle with other nationalies. its better to stay relax in your home and mingle with you friend same nationals as you. especially you can express you self and enjoy talking to them about work,life after a tiring day.
