My daughter Lila has a little Yoshi night light in her room. It sits in the corner opposite her bed, and emits a light in the color of your choosing. (These days she chooses blue.) One night as I put Lila to bed, after brushing her teeth, we walked into her room.
I turned the light off.
“It’s too dark! It’s too dark, Daddy!”
I scrambled to the Yoshi light and turned it on. She still wasn’t satisfied. So I put my hands on her, and said:
“Baby, let your eyes adjust.”
