Okay, the user wants me to translate "sends best wishes" into Thai. Let me check the rules again. The first rule says to translate all content into Thai. The second rule states if it's already in Thai, leave it as is. The third rule is to provide only the translation without explanations.
So, "sends best wishes" in Thai would be "ส่งความปรารถนาดี" or maybe "ส่งคำอวยพร" depending on the context. Wait, "best wishes" is more like "ความปรารถนาดี" but sometimes "คำอวยพร" is used for well-wishes. Let me confirm. "ส่งความปรารถนาดี" is direct, but maybe "ส่งคำอวยพร" is more natural. Hmm. Let me think. If someone says "I send best wishes," it's "ส่งคำอวยพร" or "ส่งความปรารถนาดี". Both are correct, but maybe "ส่งคำอวยพร" is more commonly used in this context. I'll go with that. Also, the user wants only the translation, no explanations. So the answer should be just the Thai text.
