This came up once in Halla's blog. I have been surprised even when living in very safe communities to discover that most of my male friends keep things like machetes and baseball bats within arm's reach while they sleep.
I know in the States, many people also have guns closeby for protection.
What about you? Do you keep weapons handy? If so, what is it and do you have and what made you decide it was important? Are you ever afraid that it could be used against you instead?
