Replying to "You better come here" can depend on the context of the situation and your relationship with the person who said it. Here are some potential responses you could consider:
Polite Response: "Sure, I'll be there as soon as I can."
Agreeing with Enthusiasm: "Absolutely, I'm on my way!"
Asking for More Information: "What's going on? Is there something urgent?"
Seeking Clarification: "Did something happen? Why do you need me to come there?"
Expressing Inability: "I'm sorry, but I can't make it right now. Can we talk on the phone instead?"
Suggesting an Alternative: "I can't come there right now, but how about we meet somewhere else?"
Asserting Your Boundaries: "I can't come over at the moment. Is it something we can discuss later?"
Playful Response: "Hmm, do I have to? Just kidding, I'll be there soon!"
Remember, your response should be appropriate to the situation and your relationship with the person. If it's a serious or urgent matter, consider addressing it promptly. If it's a casual request, you can respond more informally. Always try to be respectful and clear in your communication.
