Ideas to include
The brave song for the drive in
Their name, their new backpack, the teacher's name, and a chorus that says they can do this. Nerves respond well to a beat.
The parent's side of the drop off
For you, not them. The letting go, the empty car, the pride tangled up with the rest of it. Keep this one for yourself.
A time capsule of five
Who they are the week before school changes them. The mispronounced word, the imaginary friend, the thing they will not admit to at eight.
