My roommate in college was terribly proud of his CD collection and at the same time terribly embarassed at the small fortune he paid to accumulate it. It was like 30 or 40 CDs or something like that. I guess they were really expensive back then. He had them all lined up on the shelf in alphabetical order or something and god help you if you ever touched one of the jewel cases and left a fingerprint or god forbid touch the CD itself.
He kept giving me mix tapes which I had to pretend to listen to.
