It's gotta be something related to age.
I've found that, the older I get, the less inclined I am to remember how to plug in the wires and fiddle with the do-dads that make the bright and shiny things in my house whirr and buzz and show the pretty pictures. After getting our flooring redone last week, I had to put back together stuff like my bright-and-shiny new Sony 52" juice-sucking behemoth (not hard, since I made NOTES about where all the plugs for the Blu-Ray and Home Theatre went) and my Dell desktop (which I did NOT make notes about or, as I should've done, taken a digital picture of the backside--the CPU, not mine--for a visual representation), so now my Dell's sound is inexplicably out, leaving Bigger Blue to complain to me nightly about it, since she cannot listen to Rhapsody while reading fan fiction for hours on end instead of working a part-time job or, heaven forbid, study, study, study for college. I tried again at lunch today to figure the sucker out and still can't come up with a solution, which means NOW I have to actually find the original instructions (buried somewhere in the Goodwill-dropoff-style-piles we have scattered in and about here and there) and READ them, then get on my back under the makeshift computer table we have, down amongst the tumbleweeds of dog hair, kitty fur and dust that's been making me sneeze a lot lately.
I used to really enjoy technology. It is still fun to LOOK at the bright and shiny buttons and lights, but trying to figure out how to set them all up is a royal pain. I had to have the Sony installed by the Geek Squad guys because the very thought of trying to put wires here and there started giving me the vapors, as they used to say many years ago.
Too many options, too many labels and too many doohickeys to keep up with. Pretty soon, I'll be back to wanting to write everything on paper and use snail mail to keep up with the increasingly small circle of folks I keep up with (sorta-kinda). It'll just be too much trouble to keep up with the pressing of buttons. Think I'll order myself a Jitterbug cellphone and curl up in my Snuglie on the couch.
