SC+handkerchief+waving+goodbye

The phrase "Like a handkerchief waving goodbye", symbolizes the daughter's triumphant in learning a new skill and in becoming more independent. Even though, the mother initially feared that her daughter would fall off the bike and hurt herself, her hair streaming behind her as she heads away from her mother shows that the daughter is successful on her own. The mother realizes that she underestimated what the little girl could do, when she took a new risk and felt the joy of accomplishing something on her own.

Very solid analysis, Spencer. Love the imagery of the hair as a handkerchief.
