Ok so in front of me I have my car key....and a tone of books.....
I could build a fort out of books….that’s an idea, not really a good idea but hey it’s Armageddon, can’t be to fussy XD
Or I fight my way out with my car key!
I’ve got a coca cola can too…sharp, might hurt if it hits your head? But I don’t really want to waste it….
