Shirleyb, That's how I felt. Particularly because when the police came they said they had no seen anyone leaving my house, or around my house, or even a car on the street. (Maybe that's why I got the impression they thought I was a little 'nutsy'

) But I guess I figured better safe and feeling slightly silly than sorry.
Thanks, everyone for the support. Guess I shouldn't worry what the 'impressions' of the policemen were. Maybe I was reading too much into it.
Sorry about the bad 'quote' at the top. I can't figure out how to fix it.
