This is a photo of a typewritten page containing the following text. Wednesday, June 5, 2019. Chicago, USA. The danger of typewritten letters. This will be a short one but it's a vital message nonetheless. Keep track of what's in the letters you type and mail. At least once this month a friend has emailed to tell me that I'd already described an incident once before in a previous letter. Writing letters with a typewriter isn't like using email, which offers an archive   of your letters. So be careful.
