"I am not a dumbass! I am a human being!"
But I'm feeling a lot like a dumbass right now.
Item #1. My internet connection was down all afternoon. I tried everything to fix it. I sat on hold for 25 minutes, waiting for a technician to tell me a tree fell on the lines or something. Instead, he tells me to turn off my wireless router and turn it back on. Problem solved, I was back online. It's a good thing that the webcam wasn't on so he couldn't see how red my face was.
Item #2. Those damn CO2 cartridges. I took a closer look at them today. As it turns out, I was attempting to use non-threaded cartridges with a system that uses threaded cartridges. I've been carrying these around for MONTHS thinking they would get me out of an emergency flat on the road. As it was, they never ever ever would have worked. Ever. It was good I learned it when I did. Or maybe I'm just doing something WAY wrong and these are still the correct ones. I have no freakin' clue. I see where it's supposed to take both kinds, but it sure ain't workin' for me.
There's something to learn every day.
