pleasant stay?

finally, that girl has left my place..... its an old friend of mine, who stayed in my place for about a week until today.

i started to feel a bit annoyed with her stay, and so did my sister. i just found out some aftermath of her stay. trash dumped without sorting out in the bins (burnables and non-burnables are supposed to be desposed of separately otherwise they wont take them!), lights kept on, blanckets left in a mess, etc etc.... it does get me on my nerve.

i first met her when we were university students, that means i have know her for nearly 8 years. at first we were quite close, but after my graduation we got to see each other less and less frequently. well, this kind of thing happens sometimes. it was not that we hated each other, so i was not feeling sad or anything at that time. that was when some of my other friends lost contact with her too.
then about a month ago, she contacted me for the fist time in 2 years, saying that she was studying in london and asking me to let her stay in my place for a few days because she had nowhere to live in tokyo. of course, no reason to say no, i thought. i replied with a yes. and a few weeks later she came in, and told me she would like to stay a bit longer.
i dont know why but i cant help feeling pissed off with her every action in my place. maybe i was a bit too nervous, and so was she. maybe she might not be too rude to from some other people's point of view. maybe it was me who were becoming hyper-sensitive with an old friend.... we both have changed so much in the last few years.
last week i told her honestly that my sister was feeling a bit stressed with her stay. she said ok and told me she would leave the next week but stay here till some cheap hotel would be available. that was when i started to feel guilty. am i kicking out her? slumming the door shut at her face....? am i not her friend any more...??

friendship sometimes gets you in a difficult situation. there is no right answer, i think.
