I don't use the phone at all. My speech is unreliable.
When I'm under stress I either cannot speak at all,
or I rely on a list of 'stock answers' aimed at getting through a situation as quickly as possible.
I can't think what to say fast enough to reply, before the other person has said something else. .
My GP practice has me on their text service.
I just got a text from them, with their number blocked so I cannot reply.
It says "Please phone the surgery to make an appointment for a telephone consultation with your doctor".
Well no.
