Japanese roomate's friend

Around 11pm, when i was having my shower, someone kept knocking the door...
Fine, none of my roomates were in the room ;thus, i bathed even more faster if i could open the door though i knew that i still had to do my wash up.
As soon as i had finished my shower, the phone rang ,shocking me up.However, when i took up the phone, there was no sound at all...(Perhaps was my imagination or something else).
At this moment, a sound of the ppl hitting on my dormitory room woke me up from thought...
As usual, i knew it's Japanese girls who always find my roomate..Abruptly , my roomate sprinted out from her room and blocked my way to open the door.. :/
I barely choked out a word " WHY ?" I wanna opened the door anyway.
Again, she said " Don't open the door, my friend was drunk !" Her face expression seemed indeed in sorrow which melted me deathly .
We started to murmur like a mouse...
Ok...She know English for sure...English even is her major..
But she didn't understand my questions or whatever..She didn't answer any of my questions..NONE !
Yet, i kept on consulting with her...And finally she was willing to open the door..But , she ordered me" You should go into your room "...In fact, i nearly bubbled the words " Why i have to do that?"
Well, i was worn out;so,i was lazy to talk ..Indeed, having a severe headache and still conned on my books...
In my room, i tried to see the Taiwan shows...But my mind still thought about that drunken Japanese girl..
Ah Ha !! I had an idea...I had bought some biscuit to eat...Not share with them la...I gotta threw my plastic bag and what i saw was that pretty drunken Japanese girl was rubbing her tears in our bathroom,not in her own bathroom !! ....Omg
Chuckle...
My roomate suddenly bumped again in front of me...And said...SoRRY SOrrY & SoRRy @.@
Now she had went back her own room...i guess she will be alright after a drunken night sleep...
