I've been burgled, well I say "I". This was back when I lived with my folks and we were actually by the same guy 4 times according to his plea after he was eventually cought (I say cought, he handed himself in and confessed to a crime sprea covering 2 decades).
On one ocassion I did "disturb" the burglar, I heard a noise and went to investigate.
See there is a stark difference between what you'd like to think you will do when a situation arises, and what you actually do.
What i'd like to think would happen is that I overpower the burglar and restrain him and be the much loved hero bringing an evil man to justice.
What actually happened is I got halfway down the stairs, saw him, rubbed my eyes and did a double take to check I wasnt imagining it, and then realised that my dressing gown was not in any way an offensive weapon...
...See what actually happened, when it was real and the chips were really down, is that we were burgled when I was asleep. Therefor no amount of rational thought went into my preperation for investigating the noise I had heard.
"Why are you wearing a dress?" he asked. In credit to him this is brilliant because his 'why' question left me dumb-founded, and I stopped to think about it to give an answer, and in my half dazed state this wasnt easy. Firstly I wasnt wearing a dress, and secondly why not? It made no sense.
But that wasnt the point, he only needed a few seconds to get out.
So when you've finished being macho pondering what you'll do when a burglar visits you, maybe you ought to consider at what time of day/night a burglar might do it.
They'll either visit during the day whilst you are out, or they'll visit in the night whilst you are sleeping.
And if it takes you as many coffee's as it does me to get going in the morning then you can bet your last valued possession (what the hell, it's getting stolen anyway) that what's really going to happen is you will be at best half-asleep and totally unprepared - no matter how prepared you are.
I do have weapons, some blunted swords I keep for ornamental purposes and an autolocking telescopic baton I won in a street fight. I dont plan to ever use them, they're a curiosity and nothing more. If I take you on it'll be with a mobile phone.
