Well if we moved to the new place there's a pool house that they would be having sleepovers in which is relatively self-contained (it has a bathroom with a toilet and you stick a fridge in there with drinks and snacks and they'll be set for a night) and if they're telling each other ghost stories and suddenly those bloody eyes come on at night, it would be pretty funny for me but maybe not so much for them XD

I'm just going with the flow. If it's ours we'll get it, if not then we won't which will be fine even though I'll be annoyed about the time spent in the effort XD
