Wow. My favourite observation is the type of clothes they wear despite having migrated donkey years ago. Branded, nothing close to the locals and when they gather for coffee, they are all dress alike especially the jackets.
I seen this amongst americans and Singaporeans who have the habit of buying clothes on their trips back home.
Haha.. my wife noticed it too.. This is why wifey encourage me highlight my hair and be different.. Our suburb's frz wear rather trendy stuff, we dine together once in a while..
