There is absolutely no prompt for this conversation. David just randomly starts this one while watching Hemlock and playing World of Warcraft.
David: Apparently Siri used to answer the question I need to hide a dead body with mines, swamps, reservoirs… But someone must have done it because she doesn’t say that anymore.
Me: there is always someone that has to ruin all the fun.
David: its all fun until there’s a dead body.
