One Galleon is 17 Sickles and one Sickle is 29 Knuts... The wizarding currency isn’t too simple or practical, is it? Muggles also have struggled for ages with overcomplicated, inconsistent systems of units. But then we adapted the SI – and since then we got used to using this simple, decimal system.
There is one thing though that we still measure in strange units. 60 seconds go in a minute, 60 minutes go in an hour, 24 hours go in a day. There’s 365 days in a year, except when it’s 366, and they can be divided into 52 weeks of 7 days, with some days left over, or alternatively into 12 months of 28, 29, 30 or 31 days each, depending on... reasons.
Religious people often threaten atheists with what will happen to them after death, if they don’t convert. Yeah, cause out of all the different made-up stories about what happens after death, it’s specifically yours that’s gonna be the right one. Right...
Let’s revert that question into “what if you’re wasting your life on religious bullshit”. It’s not as scary, because if it’s the case, you won’t notice you were wrong (that’s how being dead works). Still, your current life is the only one that you know for sure you’re gonna get. Are you really willing to waste it?
