My Husband's Secretary Slandered My Master's Degree Diploma as Fake

Because I made a mistake in typing an English word in the group, the CEO's husband's secretary immediately ridiculed me that my master's degree diploma was fake, and she was angry that I got in through connections. I was about to explain that it was caused by accidentally touching my pocket, but my husband kicked me out of the group chat. I suddenly felt my face burning, [Sorry, I think your education is worse than my English. ] As a result, my husband scolded me in front of the entire company and asked me to apologize to my secretary. The secretary was about to cry, and said with an innocent face: "Brother Shengnian, don't be angry. We are a well-known listed company. If an employee like this sneaks in with a fake diploma, I will arrange for personnel to fire her now." Unfortunately, my diploma was absolutely authentic, but the president she was interested in was fake.
