At 11:42 p.m., my smart scale alerted me that a 115-pound “guest” was in my bathroom while I was at my best friend’s bachelorette party. My husband was home with our kids, and the weight didn’t match any of them. I rushed back home, and what I found left me speechless.\It was 11:42 p.m. Five of my closest friends and I were in a hotel suite downtown for Brooke’s bachelorette party.Jenna was waving a champagne flute like she was conducting an orchestra, and Hannah was trying to balance a plastic tiara on Brooke’s head. Someone had cranked the music.

Lila was filming everything for a “last single night” montage that she’d already promised to turn into a highlight reel.I almost ignored it when my phone buzzed in my pocket, but then I figured my husband, Jack, might be struggling with the kids.I looked at the screen and frowned.It wasn’t a message from Jack. It was a notification from my smart scale app.New weigh-in detected. Profile: Guest Weight: 115 lbs.I stared at the screen.Jack weighed just over 200 pounds. My seven-year-old son, Liam, was 72 soaking wet, and Ava, my five-year-old, hadn’t hit 50 yet.Even if Liam and Ava were playing around and stood on the scale together, the numbers didn’t add up.
