I think I would do OK. I'm at my Grandparent's house most of the time and they have tons of weapons (guns, baseball bats, knives, ect..) in their house. They also have shitloads of caned foods, water, and flashlights in case of emergency. The only thing I think I would have to worry about is the house itself. You see, the house is very old and it probably wouldn't be to hard for the zombies to get in. A few strong pushes on the door and it would probably break.
If I were at MY house, I'd be dead for sure. We only have 1 gun with 3 bullets and hardly any caned foods.
