Funny story, when one of the MS in my kingdom hall became an elder he gave me his old Metallic CDs because he "couldn't keep them anymore and be an elder" (not sure how he rationalized giving them to a young brother like me instead of destroying them but I was happy to have them). On his computers CD drive (yes this was way back when computers still had those) he opended the tray to put the Metallica CD in so he could show me some of his favorite songs. But the Watchtower Library was already in the tray so he had to take it out before put the songs in. When he retracted the tray back into the computer the computer crashed. To which he joked, "The computer must of had a heart attack after going from the WTL to Metallica."
Looking back, it's quite facinating to me how a person who can hold two conflicting beliefs in their head simultaneously. There's nothing quite like the Compartmentalized Logic exercised by JWs.
