Candy or library

The shortest letters are written on faces

The longest, stringed on tongues, eyes and hearts

The brain scans long letters like a librarian

It could find meanings at the beginning, middle or end

Depends on what the writers and readers see

The shortest letters, like candies in a large jar

Unnumbered colours and flavours

With time even kids know

What each candy says

To even tell apart

Sadness from despair, boldness from courage
