Surprise when coming home

It had been a hard day at work and I was glad to finally be home.

But when I stepped into the living room, my tiredness evaporated and I stared open-mouthed at my darling 19-year-old daughter lolling around on the leather armchair.

“What... what are you doing, wearing only your socks?” I stammered.

“But Daddy,” she smirked naughtily. “You know I’m always getting cold feet.”
