2020年的三月美國爆發新冠病毒疫情，一夕間學校關閉，蕾蕾再也不能去上學，只能藉由網路跟同學上課，就這樣到學期結束。很可惜無法跟同學、老師當面好好說再見，所以蕾蕾要藉由這一集感謝她的老師跟同學，謝謝他們每個人豐富了她過去這一年的美國生活！

It's so sad that Lena couldn't say proper goodbyes to her beloved classmates and teachers, because the school has been closed since March throughout the end of this school year.  So, she's using this episode to express her appreciation to these friends.  Thank you 3S and Driscoll!  Everyone of you is part of Lena's American adventure during this 2019-2020 and you enrich her memory.  We are grateful!  Hope to see you soon!
