Anyone who has (or was) a kid is familiar with the backseat chorus of, “Are we there yet?” This becomes a kind of Chinese Water Torture, and is the very reason we will never drive further than 1 hour away from Chez Ciulla. Well, at least with the kids in the backseat.

Once you allow WinXP to install updates, it generally prompts you to “restart your computer for changes to take effect.” I invariably select, “Restart Later.”
I’ll need to create a new category just for this type of thing, because while this does piss me off, it’s not nearly as bad as comment spammers, blue-haired drivers in vintage Detroit steel, or korinthenkackers.
Back in the good old days, “Restart Later” meant, “Yes, I am aware that I need to restart my computer. I just want to do it later.” Now, it means, “Restart later, but please remind me I need to do so with the precision of a mercilessly sadistic Swiss watchmaker.”
