Burn them, don't just give her the originals- get them burnt and give them to her one at a time, that way it's safer.

Yeah,
I guess that makes me the unreliable one. Boy am I lucky that there's people out there like you guys that unwittingly give up thier precious possessions yet again, thinking that maybe this time I'll take better care of your things.Huh...

Ouch. I'd get another set! One for lending, and one of your own...a precious one. Thats what I've done.

I know how you feel. It took every force within my being to let one of my good friends borrow it. I totally trust her and everything.

When she got to the fourth one, she walked up to me during school, with this look on her face. I was like "Stop looking at me like that, your freakin' me out, what's the matter with you."

She said," I might've lost the fourth disc. But DON'T WORRY. I'll replace it if I have to!!!"

Surpisingly I didn't freak out crazy bad. It ended up being underneath my other friends house, because it fell outta her bag.

But, aside from that, I totally feel your anxiousness.
