When someone says "What's up?" to you, it's generally considered a casual and friendly greeting. Here are some common ways to respond to this question:
"Not much, how about you?": This is a classic and friendly response that keeps the conversation open for the other person to share what's going on with them.
"Hey! Just hanging out. How are you doing?": This response acknowledges the greeting and shows interest in the other person's well-being.
"Hey, what's up with you?": This response mirrors the original question and is a simple way to keep the conversation going.
"Not too busy at the moment. How's your day going?": This response lets the other person know that you're available for a chat and encourages them to share how they're doing.
"Hey! I just finished [mention an activity you were doing]. How about you?": This response gives a little more detail about what you were up to before responding and invites the other person to do the same.
"Nothing much, just relaxing. How about yourself?": This response conveys that you're taking it easy and invites the other person to share what they are doing.
"Hey, good to see you! What have you been up to?": This response acknowledges the greeting and expresses genuine interest in catching up with the other person.
Remember, the response you choose can vary depending on your relationship with the person and the context of the conversation. If you're close friends, you might respond differently than if it's a casual acquaintance. The key is to keep the tone friendly and open to further conversation.
