I am an instructor in a nursing school and a verbal attack in class happened to me. The student quickly sent me an email of apology, which I appreciated. However, the class seemed to continue to shun the student (no responses to her questions/comments in online class - this silence is normally a very rare occurrence). She eventually said something in class similar to what you describe, CommunityRNBSN, and the class expressed appreciation for her apology as well. All is forgiven now and we are a team again.
