The warm blanket of senility

It seems I have taken to senility early in my life. On Saturday, I drove up to my parents' place up in the poconos to water their plants and get the mail. Seeing as they are in Europe, it's kinda hard for them to those tasks themselves, and this Saturday, it was my turn.
I did everything I needed to, and made doubly sure everything was locked and turned off, as the case may be, before I set the alarm. That having been done, I drove off to my brother's place to spend the night.
By Sunday afternoon, I began to get a nagging feeling that I forgot to do something at my parents' place. I thought about driving back up to the poconos to double-check. (as it's only 1 hr away from my brother's place, yet two from mine, I should have gone yesterday, but I digress.)
But then, I thought to myself, "Dude, your mind is playing tricks on you. Everything is fine. Should I eat now or later?"
I was able to quell the nagging about not having locked something until this morning, when it was replaced by an entirely different nag, this one about not turning off the water faucet after I watered the plants. My mind is deft when it wants to play a trick on itself.
I was 99% sure I turned the water off, as I was 99% sure the house was silent (no running water) when I left. However, I didn't quite remember the actual physical act of turning the water off.
This nagging kept growing and growing, and by the afternoon, I was totally distracted. In this case, the 1% of doubt, albeit illogical, was stronger than 99% certainty.
I knew I wouldn't be at peace with myself if I didn't check, but that of course meant four hours driving back and forth to the poconos this afternoon. I am rolling my eyes as I type at how exasperating I am.
Needless to say, everything was at it should be, and how I left it Saturday. I am rather annoyed with myself, but so be it. I can at least sleep tonight.
Also, I stopped off at Hot Dog Johnny's for dinner, so there are worse ways I could have spent my evening. Such as:
* Being stuck in a Mexican jail.
* Being dragged to a Neil Diamond-Barry Manilow double headlining concert. (This thought will not be soon to leave me.)
* November 2, 2004, all over again.
* Stuck in the middle of the ocean, waiting for a shark to take me away, after my scuba diving tour boat took off without me.
* Just like the one before, minus the ocean, the boat, and the shark, replaced by Everest, freezing, and being left by a Sherpa.
