So, a few days back, one of my team members sent me an email with the subject line. “Need your reviews on the latest marketing report. VSRE”

So, I didn’t pay much attention to the abbreviation, wrote a long review, and ended the email by asking her, “What does VSRE mean anyway?”

Her response was: “Very short reply expected.” 😃

Oops! I felt so embarrassed doing exactly the opposite.
