I read the OP, but substituted "Indonesian" for Vietnamese, and it pretty much still works.
Girls try to pass on their phone numbers as if you're the last male in the world, but it means very little, as the vast majority are only interested in you as a friend, being a potential husband is a lesser concern, but not impossible when you're as handsome and hunky as I am.
Of course, being a married man, I can't take the numbers because my wife would do something evil with two slices of bread, my sausage and one of the dogs from the estate.
