Did you have to abide by a curfew as a youth?
I did. It was 10 pm when I was young and later as a teenager moved to 12 A.M. Mother always said that the Holy Ghost went to bed at midnight and so we were to be home before the temptations of the devil could start to get to us without the aid of the Holy Ghost. Now I know that the Holy Ghost never sleeps but the principle is sound as our ability to listen to the Holy Ghost is greatly weakened by a lack of sleep and a good daily routine that includes ample sleep. Mom was very wise in putting it that way since it was not easy to forget or to dismiss.
