I am a clinical psychologist in Panama City, Florida. A few years ago, I gave my parents a fax machine and pushed them to learn to use it.
Some verbal interaction is specific to the form of delivery.
For example, some things can be said over a telephone that can not be said in person. Some concepts can be presented in poetry that would not be well received in direct conversation. Some things can be specific to the mode of fax transmission as demonstrated below. What follows is an exchange of humorous poetry or rhyme, that allowed a unique form of interaction between family members. It produced a level of warmth and identification that was very impacting , tremendous fun and helped push back the concept of time and aging.
