do you have this bad firends

It had happened to my room mate when I was in college previously. So I told this story to my late father. So my late farther advices me to take psychological step to settle this kind of bad habitual personality. I had put my prime stuffs in the locked drawer and never took it out when she was avails in the room. When she asked for it, I said I don't have it. But always in polite and nice manner with her. Next month she left me for new room and room mate. In fact I never tell any story about it to my colleagues. I heard she did the same thing to her new room mate and had a big quarrels. Later I found she no longer stay in campus hostel but rent one out campus room. Thanks to my late father, his idea really works for me.

I will avoid this kind, this is totally absurd to make as a best friend to me. Because she had past through most of the line in our area. But if you want to keep the friendship, it's up to you.
