I'm giving them the benefit of the doubt that their timing is in (some sort of) US time rather than UK time. But nobody's tried to deliver anything here today, or if they did they were extremely quiet about it -- which is basically impossible at present given how noisy our porch door is. I therefore suspect they may be using Parcelforce in the UK, which would be a shame since we already know that Parcelforce suck at delivering stuff from overseas. I may give PF a ring tomorrow pre-emptively, if I want to raise my blood-pressure a few notches.
Leave a card saying "we tried to deliver today"? Are you kidding?
