What can be concluded about getting upset over a departure?

The choice that highlights the nature of getting upset over a departure as pointless is the most fitting conclusion. Saying that it is pointless to shed tears over Michael's departure suggests that the emotions tied to the event may not be warranted. This phrase captures a common sentiment that while departures can be sad, being overly upset may not be productive or helpful in processing the situation.

In contrast, acknowledging that there is a reason for tears implies a justification for sadness, which contradicts the notion of it being unnecessary. Similarly, the idea that getting upset is necessary over a departure emphasizes that sorrow is essential, which diverges from the notion that such emotional responses may be unnecessary. Lastly, stating there's no sense in crying, while somewhat aligned with the correct choice, does not emphasize the futility as clearly as stating that it is pointless, making the chosen response more resonant with the sentiment conveyed.
