I have a client who communicates exclusively via Microsoft Word.
If she has something to tell me, I’ll receive an email with nothing in the body, but a Word doc attached. That’s where she writes her message.
Whenever she wants to email me a photo, she does so via an empty Word doc with said photo set as its background.
But my favorite thing was the first time I witnessed her visiting a website. She had me spell the URL (“W… W… W… dot…”) and with my own two eyes I watched her type it into Word, made it a hyperlink, and Ctrl click it to go there.
I was so fascinated I didn’t even say anything.
