I'm so sorry!
My realisation whilst in the shower was that you weren't up early I was up an hour late meant I had no time to check back in, and my 3g allowance has ran out on my phone and my mum --lives in the dark ages-- has no wifi!!
So,
update
During my shower I cracked open the window and spied throughout (please note bathroom window is about the same height as my kneck, no one saw me nekid) one of them left the car, couldn't tell who due to matching pjs and a hoodie with the hood up, disapeared onto the green for a few minutes and shuffled back.
They looked around very furtively like they were upto something.
On the way to school the car windows were all wide open, but no-one could be seen inside. However last time it was left like this --and I ran over gleefully to nose about-- someone was laying down on the back seat so I didn't investigate further.
On arriving home a few minutes ago, one window open a crack, lots of duvet to be seen and movement. How on earth they can be under a duvet I don't know, its rather warm here and the cars in full sun.
Again, sorry for my absence.
