on the bright side – at least you didn't wake up to a scrote bashing your back door in 😯
we got done a few years ago, beers and a curry and the front door wasn't fully secured, fekkin horrible, would have been different if we were out but all asleep until i heard our car being driven off!
we got an alarm now (i work some night shifts locally) which will phone me if it goes off (house & garage)
our area is terrible for this sort of thing, review (local police will help) your security, locks, lighting, visibility, alley gating etc
don't beat yourself up about the window – they're the scum
i now have the biggest MagLite under the bed in case of powercuts
