I know it's not my eyes, or my visual cortex, because the Stepson has noticed it too.
I know it's not the circuit that handles the lighting, because when I was looking in the fridge earlier, the light in the fridge flickered in the same way, so that means it's something upstream of my fusebox.
I'm conceding the possibility, therefore, that I'll lose power to the house at some point. This will take down my Internet connection, since certain bits of infrastructure here aren't on the UPS.
We'll wait and see.
In other news, we have birthdays:
Last week for aeglefinus, moominmuppet, camies and darth_tigger -- I hope you all had a good time.
Around now for sorchar, swisstone and sakinisapunk, and next week for scarlatti -- this is the longest consecutive series of birthdays of people on my friends list starting with the same letter. Am I the only person who notices things like that? Warmest congratulations to all four of you.
