<human>: Can you provide a brief overview of the text?

Well I guess the title lied; she stops when she's sleeping. I live in a house with 3 other girls, and we have all wondered what we should do but can't seem to come up with a solution. 

Let's call her "Catherine". Catherine sings from the minute she wakes up until the minute she goes to sleep. Not just quiet humming to herself...like full on, sing your heart out style. And it's not just in her room...no. It's in the kitchen, the bathroom, the living room, everywhere. 

She's Vietnamese and recently immigrated here a couple years ago, so the fact that it might be a cultural thing (is it?) is what is keeping us from outright asking her to stop. It's just strange because she keeps to herself, doesn't have alot of friends, and is not the type you'd generally think of that would sing 24/7.  

It's starting to drive us nuts because we are all in nursing school and have tons of studying to do. I don't think I should have to have headphones in all the time in order to get my work done considering it's my house too...

Reddit, how do we approach this?
<bot>: One of our housemates won't stop singing and it might be a cultural thing. How do we make it stop/be more bearable?
