Twenty minutes is such a short time, yet it can be a long time or “just enough” time, depending on what, and why and where, and all that stuff.
How about when it comes to sleeping? It doesn’t seem like twenty minutes can be enough, however, I find that a twenty minute nap is what gets me through the day. I somehow am not able to sleep for more than three hours at a time. At least that’s what has been happening the past three or four years. Even when I am dead tired, I can’t sleep any more than that. Therefore, to make it through the day, I end up needing to nap, at least once, during the day. That nap seems to be precisely twenty minutes. Even if I set my clock for a forty-five minute nap, after twenty minutes of sleeping, I’m wide awake.
I guess it’s a sign of my age? Is that what happens when we get older? I remember years ago, when I was first married. My ex had a good friend that was about ten years older than he was so I guess he was in his late thirties. A few times, we had him and his wife and their little boy over for dinner. We were used to eating later than earlier but when Conrad and family came over to eat, it had to be earlier because he went to bed early. He would tell us about how he had to be in bed by about 9:30 or he would just drop and then, in the morning, he was up way before dawn because he couldn’t sleep more than a few hours. He used to spend time reading a lot while the rest of his family was sleeping. He read the classics and also contemporary bestsellers. My ex used to make fun of him and say that it was because he was so old that he needed so little sleep. I guess my ex will think the same of me now. I’ve gotten old and so I can’t sleep. Ah…..but I would have to remind him that he’s five years older than I am so ha ha!
Oh well, I guess I should run off and get my twenty minutes!

For some reason I can tell myself to take a nap for 30 minutes or an hour or 45 minutes and I usually wake up pretty much on the dot. Have no idea how that works. I rarely nap unless I’ve lost sleep the night before, but when I need one I need it. I describe it as being pulled under.
Enjoy your nap.
