This week I've been semi-battling a cold. As a result I haven't been sleeping well. Finally, last night, I was able to get a good night's sleep. I felt pretty good this morning, got up and did multiple tasks, and then the energy wore off. Completely. Before I knew it I was resting lazily, I didn't actually have much of a choice. So, today I am grateful for rest, which I've always found odd that 'rest' is sorely lacking when I am sick.
I guess that is just one of life's trials.
