CDs: the new obsession

I don't really understand why Judah becomes so fixated on certain things. But for whatever reason, the current fixation is CDs and CD players. His favorite activity is opening and closing CD players and putting CDs in and taking them out. Who knew this could be such a profoundly absorbing activity. He is also somewhat interested in listening to certain albums and songs, but he unfortunately is missing an important concept: that a song he wants to hear is located on a particular CD. So he often becomes enraged when he asks to play a song and I dare to suggest that he relinquish the CD he's holding to put it in the player. Ah, logic, what a tricky thing.
