Good to know -- thanks. I once had a knock on the door, late late at night, asking if they could borrow an egg. I asked who they were and where they lived. Unfortunately for them, fortunately for me, I KNEW the household of the house they mentioned and knew no Brian lived there............later, after I reported to the police, I found out they had been going around to houses and uses that excuse to get in and rob the inhabitants!!!!! Better to be safe than trying to be a good neighbor!!!!
