TLOML and I had a little help this year, as Lady P decorated some trees. She did ask several times if she could 'just eat it?', which was a fair question, to which we said no. Not yet.
after last year our fears of collapse meant we didn't decorate till Christmas Eve. So she only had to wait one day. And the house only needed to remain upright for 24 hours.
In short, I think we have perfected the strategy.
