Yeah, I'm not sleepy. After taking a nap, I put food in the microwave, then evidently was distracted by something shiny or had some other reason why I left the kitchen. Minutes later, I went back INTO the kitchen and lo and behold, the food was still frozen.
Hmm. Seems like there's no substitute for actually setting the microwave and hitting the start button, is there? Apparently, I'm still not done taking that nap, even if my eyes ARE open and I'm sitting up.
