Yes, there is a difference between talking about someone and talking about what someone did to you. The distinction lies in the focus and content of the conversation:
Talking about someone: This refers to discussing an individual, their actions, or characteristics without necessarily involving yourself directly in the conversation. For example, talking about a colleague's accomplishments, personality traits, or behavior in a general or objective manner would fall into this category. It may not necessarily involve any personal impact or experience.
Talking about what someone did to you: This involves sharing a personal experience or an action that directly affected you. It is more specific and personal in nature. For example, if someone treated you poorly, helped you, supported you, or affected you in any significant way, talking about it focuses on how their actions impacted you personally.
In summary, the key difference is that "talking about someone" is more general and detached, discussing the person or their actions without necessarily relating it to your personal experience. On the other hand, "talking about what someone did to you" is more specific and involves sharing how the individual's actions directly affected you personally.
