So I've had a bit of a cold and I've been a bit malaised. I've been very slow and hazy. I also managed to get pink eye in both eyes so I look nearly demonic with how red they are.
So I went to Wal-mart while my wife was making a movie and ended up getting a fair number of snack foods that she liked (among other necessities for the house). It was a brief trip so most of the stuff looked snacky. I was in a haze with my headphones on (listening to science podcasts) while checking out. The cashier kept looking at me funny but I didn't think anything of it. She asked me a few questions and I was a) distracted by my podcast b) slow on the draw from being sick c) having trouble hearing her low murmur.
A few hours later it has finally occurred to me. She must've thought I was high out of my mind. I was spacey as hell, red-eyed like crazy and buying snack food. She though I had the munchies. She told me to have a good night with a sort of a sly grin that didn't make sense then but certainly does now.
