I caught my 21-year-old daughter sneaking out of our married neighbor’s house at 3 a.m., and what she confessed the next morning left me disappointed in her. Last week, I got up around 3 a.m. to grab a drink when I saw her quietly leaving our neighbor’s house. She crept across the yard and slipped back into our house through the basement door, clearly hoping nobody would notice. Our neighbor is married and around 30 years old. His wife’s car wasn’t there that night, so I assumed she was away.
