Being Catholic too, I totally relate! "Catholic churches were dark & somber in general, so it makes sense that I'd think that about the organ playing."
My parents being devout Catholics allowed me after my confirmation to attend church by myself (lols) because I didn't, but the the funny thing is when I actually did go, and they started that tithing BS mid-mass, with somebody playing that hoaky organ music (hoaky church, not hoaky rolling rink) they would hold that basket on that 20 foot-long arm (I swear that pole was as long as a football field!) rattling that basket in front of me for what seem like hours, I was like, can I help you? I'm like, this is my 7-11 money!
