I am having another "middle of the night" evening. When I got home from work, I took my dog outside, then came back in and fed him. He was so happy to be with me. I was feeling bright but not hungry, so instead of fixing dinner I sat in the recliner and snuggled with my affectionate dog, intending afterwards to try a new knitting pattern. It was so cozy and warm to cuddle with him that I quickly became drowsy and then fell asleep. I woke up about four hours later and have been awake now for a couple of hours.
This has become a pattern for me lately. I usually do eat dinner before falling asleep, but I sleep through the early evening, then wake up for a while late at night, then sleep again till morning. Neither good nor bad, I guess, as long as it all adds up to sufficient sleep.
