three o'clock
John laughed terribly at his own story -- the women did n't laugh , nor grandpa . My uncle did , and I that 's all . Then Aunt Caroline helped grandma get supper and we had a lot of fun and they drove home . The next day grandpa started early for Petersburg , so as to be back by three o'clock for something . And my uncle and me was getting ready because we was goin ' to drive to Blue Lake that night , pitch the camp , and fish while it was quiet . So we had to grease the wagon and do a lot of things . And grandpa was to bring Mitch .
