I hunted deer for years with a borrowed shotgun. I've hunted pheasant with a neighbor using one of his guns.
I guess I think different about material objects than do most. They are meaningless to me. People matter, stuff doesn't.
If I borrow, I endeavor to return it in better condition than I received it. If I lend, I expect to never get it back (even though I almost always do)and it's a bonus if I do.
