If you have a gun and at least some ammo and you also think you’re likely to need to defend yourself with weapons then I think the gun’s going to be better for so long as you can keep it operational, than a crossbow. Both need skill to use but I’d wager myself having a little more luck with the gun and it’s probably going to be a lot more deadly and if you miss you have a little more opportunity to try again than you might with a crossbow. that’s going to be awkward to try and reload in the heat of the moment, by yourself.

Touching and insightful stuff, the double reference to killing is a little messed up though, especially your friend that went as far as suggesting a place to bury the body that guy sends a chill down the spine.
