Someone, in a mail including my boss and other managers, complained that my replies were too short

To which I replied

‘They are as long as they need to be.’

So she went ‘A little warmth would help communication greatly’ or some other bullshit.

So I added automatic top and bottom text to my emails and for the past idk 10 years or so, all my emails start with ‘Hi,’ and end with ‘Cordially.’
