Yeah I personally want to own a gun when I am living on my own. Because when I was young, but young enough to remember, my dad was out on a trip (he is a fisherman) and had been gone for about two weeks, and my mom and I were home alone in the house, and some psycho came up to the door screaming that he was "hurt" and to let him in.
He banged on the windows and was looking in at us, and my mom was scared, and called the police, but by the time they got there he was gone. It was scary. Then later that week, we walked in, and half of our belongings were gone. We'd been robbed of almost everything, as hard as that is to believe. And we were pretty poor, so it blew.
And it was so scary knowing he could come back, we assume the incidents were connected somehow. So I've always wanted a gun around, just in case.
For protection you know, defense. But I only worry about future children... finding it, it's almost impossible to make it totally safe, and still available to use if I had to. But I have nothing against guns. If they're totally illegal, people will get them anyway. I'd rather people be educated about them how to use them and what not.
