Huh? The pho place my wife and I eat at on Friday nights is run by a very nice American family of Vietnamese ancestry, and their little girls run all over the restaurant while we're eating. It doesn't bother us; the kids make a little noise, and the toddler sometimes fixes us with a baleful stare, but they never interfere with our meal in any way. Of course, the fact that they are both super cute doesn't hurt!
Why do little kids glare like that? One of my nieces is great at looking at me like she wants to eat me. Her twin sister has never given me that look. (Maybe my sister is feeding one and not the other.)
