Cloakboy,
Ive learned a long time ago never to let anyone borrow music gear unless it is someone you really know and trust like a close friend(bandmate) or family member. Only about 3 months ago, some dude asked if he could borrow my chorus effects pedal at a recording studio. I was going out to lunch with my bandmate, so I told him to return it to studio A when he was finished. When we came back from lunch, the guy had left with me chorus pedal. The SOB stole it and since he wasnt the one that logged his name for the time, we couldnt track him down.
Yeah, I was partially naive to let him borrow it, but before that I never had a bad experience with fellow musicians. If I were you, I would buy another mic. Maybe you can use the old mic to mic up an amp or a snare or something.
