Dear Professor,
I sincerely apologize for missing the meeting yesterday. I had been working on my research report, and I was completely focused on it — so much so that I accidentally forgot about our appointment. This is not an excuse, and I understand the inconvenience I caused. I truly value spending our time together, as our meetings always help me move forward. Additionally, it took a long time for my response to arrive, and I regret that as well. Going forward, I will manage my schedule mor
