Well, you went to correct someone's language, and you were wrong. ??
She defined relic in the most common, literal sense (an object left over from the past). The word comes from Latin for "remains" and has been used to mean "something left over from the past" for centuries. I trust that you really can look it up yourself and I'll spare you the linking ... but if you're really interested in correct vocabulary, you probably should look it up and think about it.
Of course you're hardly the first person to ever have acquired a slightly off-target idea of what a word means and been convinced of it. I thought apprehend meant "to worry about" for a long time.
The police apprehended the suspect ... I thought that was incorrect usage and only by the grace of god did I never speak up to correct anyone, before I looked it up myself. Especially I'm glad that I didn't go to correct someone and then make a general dig at them in the same breath. ;-)
