The first piece of evidence suggests that the speaker, who was eighteen years old at the time, did not have any friends her own age. The speaker implies that she was not popular enough to be invited to social events by boys in Charleston, indicating that she may have felt socially isolated and excluded from her peers.
The second piece of evidence suggests that the speaker had a difficult relationship with her mother and that her mother had given up on her at an early age. Despite this, the speaker was able to achieve some academic success in high school, but her mother did not notice or acknowledge her achievements. The evidence suggests that the speaker's mother had low expectations for her daughter, which may have contributed to the speaker's sense of isolation and alienation.
Together, these pieces of evidence suggest that the speaker may have struggled with feelings of loneliness, isolation, and low self-esteem due to a lack of social connections and a difficult relationship with her mother. The evidence also suggests that the speaker may have been able to overcome these challenges through her academic achievements, but that her successes went unnoticed by her mother.
