" Duay, jark noy ku pi ha " it doesn't make sense that you feel bad about. I think you and your friend are closer friend or best friend right? Some time we use a word "Duay " to our friend or people who's younger than us just for joke, fun and teaching. How come parent say " Duay " to their little kits? You should understand " Duay " is not only using to people we respect or high level and older than us, we can use with every one.
