I'll have to think about this one...it's been a few years and gradual enough that it all seems "normal" at this point.

Sally, we used to ignore strangers knocking (the old hide behind the curtain trick) but in our area there's been an increase in daytime burglaries where the bad guys knock first...if you're home, they ask for directions or something. If nobody answers, they try to break in. Grrrr.

Sorry for the hijack.
