a case of sour grape?

Please provide me with more context! To understand if a situation is a case of "sour grapes," I need to know:

* What happened? Tell me about the situation you're referring to.

* Who is involved? Are there specific people or groups involved?

* What is the alleged sour grapes? What is the person or group supposedly feeling bitter about?

Once you give me this information, I can help you determine if it's truly a case of sour grapes or something else entirely.
