A rush of excitement flooded through Carol as she bypassed the parental controls on her daughter, Lily’s, phone. It had been a struggle, but she'd finally cracked the code to unlock the mysteries held within that gleaming rectangle. She bounced on the balls of her feet, an anticipation building up inside her.

The first few posts on the private Snapchat account were pictures of Lily's friends, all grinning and looking silly. She felt a surge of warmth as she recognized their faces, girls she knew and loved.

Then she saw it: a selfie of Lily, her hair a mess, wearing a face mask, and looking like she was having the time of her life. Carol wanted to frame that picture. She took a screenshot for herself.
