Oh, also, on the subject of home defense against zombies... when I was a teenager & still lived with my parents, we lived over our shop, & there was a bar/restaurant next door.

One night, I heard a scary noise out back, & looked for something heavy.

I picked up a hand-drill in one hand, & a hammer in the other, & tiptoed into the dark yard. There was a rattling sound, I was sure.

I looked about the yard, no one there.

I opened the back gate & peered left & right along the driveway.

I decided not to creep next door & check there, 'cos I'd started to think that all I'd heard was water dripping into a broken plastic flowerpot, rattling in the gutter.

I went back to bed.

Next morning, I was leaving for school, when I saw there were police outside the back of the bar next door.

A man WITH AN AXE had smashed through the back door of the place & stolen bottles of booze & some cash.

Hand-drill & hammer teen against AXE MAN... I don't fancy my chances!
