How can Dee's attitude toward her heritage be considered authentic?
She always seems to be labeled as shallow and materialistic but her desire to only want the quilts that were hand-stitched by her Grandma shows she's sentimentally attached to that past...can you provide more evidence of how she actually appreciates her heritage?
No. She rejected her heritage until it became a quaint ornamentation for her new persona. She is not truly proud of where she come from, she just seeks to gain "street cred" with her new friends.
