Constantly see people online talk about "when the robber comes thru my door" or whatever, and some of it is memes, but a lot of it is just people legit discussing what the "best weapon" to fight robbers breaking into your house at night would be - Giving it so much thought as if it is a legitimate concern. So is it? Does it happen a lot?
I've always considered writing a post-apocalyptic story based around this. One where it's actually a group of survivors doing community outreach that manage to survive and have to deal with violent lone wolf freaks every now and again. Instead of the usual Burgerland story take where the community centred survivors are weak, small bean gentle folk who can't deal with the harsh reality of the wastelands.
