@Mum of two this gives me an idea...
Let's have a tattle sweepstakes (sort of)
How will the new house be revealed?
Vote with reactions:
Pan in on front door/any of the decs (in or outdoor) and out to new house
Montage of going to bed in old house and waking up in new house
Nothing happens because they aren't moving
"Rent" a holiday cottage but reveal that they actually bought it
They go away on holiday then come home to new house
Montage about loving the house but needing bigger for the family/worked so hard for their dreams building up to house reveal.
Something that hasn't been listed and you're going to quote this post and tell me so we know who wins this game when the time comes!
