I'm not afraid of robbery. I live in a quiet neighborhood and have those fake anti-break in alarm stickers over my windows.
And then again, half of the people in my household are very light sleepers. If someone tried to break in from the back, I'd hear it and wake up.
Although I do have my old bokken and a few broken legs from my old table that I was going to use for a certain project but never got to. Any of these objects would make pretty good clubs, and I'm used to swinging things around.
And I live right next by the kitchen, so I have a knife rack available within a second of me getting out of my bed. And I could use them, too.
So, yeah. I sleep with a locked door, have a number of various clubs of different nature (bokken since it's a glorified stick, table legs, metal tennis things although they wouldn't do) right by my bed, and a lot of modified weapons a wall away from me.
Oh ya, and obviously enough the phone and the cellphone are within a hand reach away from me, and it should probably be your first reaction to someone breaking in unless they get scared away and run out the moment they hear you get out of bed or what not.
That should be good enough, but then again I've never had someone break into my house/apartment in either Russia or Canada.
