Mine are:
That it will snow and tomorrow's tesco delivery will not make it through (unthinkable nightmare- am working, and no time/ inclination to shop and lug the lot home by hand!)
That dc's will be somehow disappointed with presents
(Illogical one) that we will all come down with vomiting bug and that my carefully planned out Christmas will be ruined
That the tree will be bald soon- despite spending extra on "non-needledrop" Nordmann fir, it seems a bit more fragile this year than in previous years! If you touch it, it sheds loads!
That our best friends who we always spend the New Year with won't be able to make it through because of snow.
That I have spent far too much!
What are you silently fretting about?
