At a grocery store, Karen sees her friend Susan put a carton of eggs into her shopping cart. Later, while Susan is in another aisle, an employee accidentally knocks over her cart, breaking some of the eggs. The employee quickly replaces the broken eggs with a new carton before Susan returns. What will Karen think when she sees Susan checking out with unbroken eggs, and how does this differ from Susan's perspective?

Respond very briefly.
Karen, having seen Susan initially put a carton of eggs in her cart, might be confused or surprised to see that the eggs are now unbroken at checkout. She might assume that Susan noticed the broken eggs and replaced them herself or perhaps question her own memory, wondering if she was mistaken about the eggs being broken in the first place.

On the other hand, Susan, who is unaware of the accident that occurred while she was away, will have no reason to think anything is amiss. She will believe that she is purchasing the same carton of eggs she initially selected, with no knowledge of the breakage and subsequent replacement by the store employee.

The difference in perspective here is based on the information each party has: Karen has incomplete information about the incident and the resolution, while Susan lacks the knowledge that the incident ever happened.
