Off the grid writing skill / improve letter box

I think writing only in computer is very illogic. As long as we have paper and something to write then it is enough. We already have homework and personal journal so notebook wouldn't hard to make. Typesetter could use computer animator too.
I wish we could send letter and gift though letter box. I mean we already use they when we send song or new book for public so just normal letter wouldn't be hard. We already could donate knittable craft by it. We got postcard and fan gift though box in get in famous. Love letter is classic and handwriting one feel more romantic too.
Homework could do anywhere also digitalistic sketchpad. Notebook gonna be cute gameplay like you writing poem or something during travel
