So I get a call the other day from my Mother the other day and it goes something like this "Hey, Are you off today? Did you drop by our house?" Me "No. I'm at work. Why?"
Well apparently here's why.
Dad was downstairs on the computer and thought he heard someone walking around upstairs, so he left the house and called the police. The cops showed up 20 minutes later (for a hey, I think there's someone in my house, call) and cleared the house while having dad watch the front door. In this case no one was there and dad was just hearing things. Funny that, since he has tinnitus and is hard of hearing, yet he adamantly denies he can't hear and refuses to get a hearing aid or even get his hearing tested..
Now, imagine someone actually WAS in your house and wanted to hurt you. Even if that 20 minute response time is cut way, way down it's going to take at least 5 minutes. What are you going to do in the time between the call and when the cops arrive?
Why guns? That's why guns, folks!*
*Although in dad's case he's vehemently anti gun and I sure as hell wouldn't trust him with one.
