I write emails for an hour sometimes. Some things you want to have in writing so you can point back to it later. I work in a government position and for a lot of the folks I deal with I need to be able to show I told them this on this date and the trail that goes along with it to be able to take action on what they did that they shouldn’t have or didn’t do that they should have. That hour on an email could prevent or shorten tons of meetings and headaches. Just depends on your job.
