To Sit in Contemplation of One's Naval

Deliveries were planned in for AM - that means anytime between 9.00am and 1.00pm (12-1 is NOT AM but this was not worth pointing out). Deliveries were going to an address that is not my office but at a currently unfurnished and unstaffed learning centre - meaning I had to wait for the deliveries to arrive. Why is it that when something is being delivered they give you a date and a time scale (between ... and ...) but you are always the delivery at the end of the scale? Why don't they just say they will deliver at 1.00PM?

My naval is an innie, I can twiddle my thumbs equally well forwards and backwards, it took 12 police officers to arrest one bloke in the street outside the learning centre windows today, the carpet tiles are all the same colour but have been laid with grain going two different directions, all the light switches are at the front of the room apart from the central line which is by the disabled toilet...and then they rang up to say there's been a delivery mix up and they won't be coming today.

We are patient, we are calm. We are going back to do some real work.
