Sue Lor: All the people in this house are very traditional. Number one: never touch a Hmong person on the head. Not even a child. The Hmong people believe that the soul resides on the head, so don't do that.
Walt Kowalski: Well... Sounds dumb, but fine.
Sue Lor: Yeah, and a lot of Hmong people consider looking someone in the eye to be very rude! That's why they look away when you look at them.
Walt Kowalski: Yeah. Anything else?
Sue Lor: Yeah... some Hmong people tend to smile or grin, when they're yelled at. It's a cultural thing, it expresses embarrassment or insecurity. It's not that they're laughing at you or anything.
Walt Kowalski: Right, you people are nuts.
