@parentsnet123 - Ah, Thank you!
25 pages? Moi? Well, I do drone on! 
The YABU/YANBU were a fat fingers mistake, I didn't mean to have voting, seems to attracts some argumentative bunnies.
Thank you for your nice words Parent, I got shaken, taking in the possible implications, but I'm in a better place now.
We've done stuff today so we have less of an easy prowling ground for an intruder and have a new dog to look forward to. Stopped me feeling hopeless.
I've put in place a nifty little trick (thank you John Le Carré) that will let us know if someone has come round again or not.
That creep is not going to stop us enjoying our home.
He's shown us how vulnerable we were and we're doing something about it, which is a plus.
I've had my dark hours but don't feel I've been hysterically screaming blue murder, if so, sorry, must be me being french.
One thing you can say is that when a stranger goes out of their way to lurk under your windows, they're sick in the head. That comes in all shapes and sizes from the most benign to the more scary.
If they managed to lose their phone and give the game away, they're probably thick and scatty and not that focused, a good thing for us, surely.
We'll never know. What matters is that we learn our lessons and move on.
I am glad the thread has provided you with some distraction from the ambient shit storm, you're very welcome to that
. We'll take whatever we can at this stage. Besides, there is far worse going on than this, right now.
The thread has helped me lots and kept me going when no sleep, it's been interesting and great for processing stuff, ( DH is not a 'dweller').
Thanks for the Mowgli quote, I like it.
