@P E Dant,
												False.  I keep one pair at the door in case I have to make a quick exit to deal with intruders on my property, and another pair beside my bed in case they get through the door while I'm in bed.  
Yeah, I know what you're thinking.  You're thinking: where the hell does this guy live?  I live in a safe enough location, but it's like the yeast jar thing--what if?  I mean, what the hell If?
