Here are a few ways you can respond to "How was your day?":

1. Simple and positive:

• "It was good, thanks! How about yours?"
• "Pretty great, thanks for asking!"

2. If it was busy or tiring:

• "It was a bit hectic, but I got a lot done."
• "Long day, but I’m glad it’s over."

3. If it was relaxing or enjoyable:

• "It was really nice and relaxing today."
• "Had a great day, just took it easy."

4. Honest and casual:

• "Honestly, it was kind of rough, but I'm hanging in there."
• "Not bad, just the usual stuff."

If you want, I can help you craft a specific response based on how your day actually was!
