Suppose Emily and Sarah were roommates in college. They shared a dorm room and became close friends quickly. However, one day Emily accidentally broke Sarah's favorite mug and tried to hide it. When Sarah found out, she was upset and confronted Emily about it. Emily felt terrible and apologized profusely, offering to buy Sarah a new mug. Sarah forgave Emily, but their friendship was never the same after that incident.
Can we infer that "Emily and Sarah never spoke to each other again after the mug incident."? Yes, no, or maybe?
