That housemate again!

I dunno what's got into her..
Yesterday, she sms me to wake her up..din noe until she called me...but i din wanna pick it up.so i left it like tt..after tt, i off my phone.if she asked, i planned to tell her that my battery went flat.
when my roommate came back, she told me, "Hey, u were right! She smsed me to wake her up..."because the night b4 i asked my roommate whether she gave the housemate her number..she said yes..I told her, "die la die la..she's sure going to sms u to ask u to wake her up.."
My roommate gave me a look..
den just now i went back to my room to bathe andget my laptop to come to my future room..gaga..when i came out from the toilet,she shouted from the room, "hey sarah, wad time u going to slp?" i told her b4 12...
sarcasticly she said,"like wad time? 6 or 7?"
i told her 10 or 11 lo...
she said," b4 u close your eyes, wake me up ok?"
In my hear, i was thinking,u want me to wake u up, den u ask me properly la...u angry at me or wad?say la..
den y must your 1st sentence be wad time u slpin?if u wanna wake me up then u say la..dun bother asking me wad time i slp..den when i wanna slp i'll wake u up..
I've been waking her up nearly everyday eversince i moved in to that room/house!
She even told me that day, "my frenz call me to ask me whether they need to wake me up anot using the phone, thens he told her frenz say no need. Got Sarah can edi..she can wake me up."
THIS WAS WAD SHE TOLD ME..wad does she think?she says she treats me as her family member..den why does she tell my roommate, dun bother about me when i'm slpin..just on the light...
I really dun understand..
