Supertween has been singing a single line from a Sound of Music song for days.

“So long, farewell, auf wiedersehen, good night. I hate to go and leave this pretty sight.”

I offered to look up all the lyrics to the song.

“No. I like this part. So long, farewell, auf wiedersehen, good night. I hate to go and leave this pretty sight.”

She sings it in the morning while getting ready for school. She sings it when she gets off the bus in the afternoon.

“So long, farewell, auf wiedersehen, good night. I hate to go and leave this pretty sight.”

Last night, she made a big red bullseye store run with me. I grabbed a box of cereal and she sang.

“So long, farewell, auf wiedersehen, good night. I hate to go and leave this pretty sight.”

I stared at the shampoo selections and she sang.

“So long, farewell, auf wiedersehen, good night. I hate to go and leave this pretty sight.”

I scowled at the razor blades priced as though they are made from unicorn horns. Supertween sang.

“So long, farewell, auf wiedersehen, good night. I hate to go and leave this pretty sight.”

Suddenly, from the CD section across the aisle, a familiar tune began to play.

“So long, farewell, auf wiedersehen, good night. I hate to go and leave this pretty sight.”

A bullseye employee with an ear to ear grin slipped out of the music department and floated off toward the cameras. Supertween squee-screamed in that way that only tween girls can and I made a bee-line for the laundry detergent aisle. Well played, bullseye employee with a brilliant sense of humor. Well played.
