That`s what my first talk with a deaf person looks like. Actually looks like!
In the long run, it would cost a big amount of paper and pens, and lost of patients to communicate that way. Lots of details get lost expressing yourself by writing down what you want to say in a conversation, but to look further, something remains.
Also, you become creative searching for solutions, finding new ways to run the talk. Time begins to play an important role. Writing takes time, you begin to find shorter versions of what you want to say. Writing, mimic and gesture begin to meld to complement one another.
