The kittens have tons of toys but yet they would rather play with my pen.🤷♂️🤣
For the younger generation that is an instrument we use for writing down words.
@Tacitus_Kilgore Schrodinger's pen.
It both has and does not have ink at the same time. When you start writing you just make a groove until you make a little scribble in the corner to the ink flowing.
