" i was like that ship before my education began, only i was without a compass or sounding-line, and had no way of knowing how near the harbor was."
Explanation: this could be confused for a metaphor being that metaphors and similes are like twins. What you need to remember is that a simile compares two unlike things using like or as. And a metaphor compares two unlike things without using the word like or as. therefore in this case because she uses "i was like" that is the line with the simile.
