My Flatmate

Sometimes I don't know what to make of my flatmate "W'. Some days she is the sweetest person in the world, very kind and caring. She has been staying with me since March and is a student from Hong Kong, studying English. She is a tiny thing, and quite cute, although not my type. She looks young and could pass for an 18 years old, despite the fact that she's 35. (Her boyfriend looks as though he;s in his mid-20s, so I suppose we could say she's a cougar!) Her English is not very good and a lot of the time I say very basic things to her and she will give me a WTF face, meaning that I have to repeat myself and simplify my message. She does try very hard though and has picked up a little bit of 'strine'. The other day when she saw me, she greeted me with a 'G'day mate.' which I found much amusing.
To look at her you would think that she is a delicate little flower, very dainty and lady-like, yet she seems to be a big tom-boy. Let's face it, she's already a bigger slob than I am, which is saying something. For example today she left her bra and undies hanging up in the shower, whilst the other day I came home and saw that she had left  mess in the toilet for me to clean up. Another example happened a few weeks ago when she had a weeks break from school. She spent that week in her pjs (they are old lady pjs too) on the couch, watching TV and drinking beer. She farts and burps as well as any bloke too. I do find it all to be very hilarious too.
