The stars came out: she did not notice. On the way back she met her mother, out of breath, come to look for her, and scolding. “I did not see till I was home, that you were not there. I thought something must have happened to you.” And Sibia, bursting with her story, cried “Something did). I found a blue bead for my necklace, look!”
