For three years, Mark told his wife he visited her sister Karen every Friday to fix her “broken kitchen sink.” She never questioned it until their young daughter casually mentioned that Daddy had also been at Aunt Karen’s house on another day.
Suspicious, she secretly followed Mark the next Friday. She found his car hidden in Karen’s garage and looked through the kitchen window, where she saw Mark and Karen embracing intimately. She took photos as proof and confronted Mark that night.
When shown the photos, Mark admitted there was something she needed to know before she left him, claiming Karen had discovered a secret about her three years earlier—but the story ends on that cliffhanger.
