Bibliophile

Three days ago, I met an acquaintance of mine who I had not seen for a very long time. We were not talking much back then, so we didn't know each other very much. So we were in this one place where we had to spend a lot of time together as we were coming to support a friend of ours, and she saw me read a book on my Kindle. So this friend, the acquaintance, then asked if I was just reading a book because I was bored or I loved reading books. Then I told her that I do love reading books. To my surprise, she called me bibliophile. So I didn't know what that was. Imagine me reading all this while, yet doesn't know that a person who likes reading is called bibliophile. Yeah, now I know.
