i have to agree with nearly everyone else. if i'm doing someone's makeup using my own products then that's fine, but i have to draw the line there. i can't let friends just walk away with my makeup unless its something that i've given them to have, other than that, it's a no-no, just like my cd's or my dvd's, for some reason i just have those friends who don't like to return things, and i'm not one of those friends. i actually return things because i don't like the burden of having someone hunt me down for their stuff back.
