i sent off a difficult email today and a bit worried about the response . oh , do n't worry . you 'll get good response . what was the email about ? it was a personal email about some tough life things . they do better if i email versus face to face . i am very anxious about the response as they have a temper . hope ! you 'll get a good reply !
The anticipation of an angry response from the recipient due to their temperament is the cause of the anxiety.
