This is an incredibly heartwarming video of students surprising their teacher Dr. Brown during their last Zoom class of the fall semester with signs expressing their thanks. When the class started and all the students’ cameras were off, Dr. Brown initially thought maybe he’d accidentally done something to mute their cameras or upset them. Then, SURPRISE, just the opposite. That was really, really great. *raising glass* To more Dr. Browns, and to more students like these ones.
