I Am Xi Xi's Mother

The children were led out in orderly rows promptly at 5 PM and Xi Xi was last in line. She was the tallest in class, taller than the boys in class, so she liked standing at the back. She was already used to standing at the very end of the line.

Xi Xi carried a small yellow backpack and her robot in her hands. She walked very slowly and there was a gap of about seven or eight meters between her and the student in front of her. If it weren't for her teacher turning back to yell at her to hurry, she would have already been separated from the rest of her class. 

She would carry this robot wherever she went. This was her best friend; her only friend Du Du.

Xi Xi slowly walked up to the school gates and stared intently at the floor as though she was thinking about something.

Suddenly, a small boy appeared in front of her. This boy was from the class next to hers.
