OK, it's 9:06 p.m. here and no UPS yet.
Any nuclear engineers, physicists or material technologists in the audience ?
For them I shall say that I have just transitioned into a
nucleate boiling state.........
localised overheating and cracking appears imminent now.

I've been through that drill more times than I care to remember. UPS tends to come here late in the day, and sometimes it's very late. The day I stayed home to wait for my Super 10D (1DsMk2). Around 9:30, the tracking info on their website changed from "out For Delivery" to something to the effect that the package was missing and would be delivered the next day. The next morning, we were at the UPS terminal, and we waited for them while they went and found it for me.
