When someone says, "I had a great time with you," it's a positive and complimentary statement about your time spent together. Here are some ways you can respond:
"I had a wonderful time too! Thank you for such a great day/night."
"I'm so glad to hear that! I had a fantastic time as well."
"The feeling is mutual! I really enjoyed our time together."
"It was a pleasure being with you too. Let's do it again sometime!"
"I'm thrilled that you had a good time. I did too, and I appreciate your company."
"I had a blast with you! Thanks for making it so enjoyable."
"You're such great company! I'm looking forward to our next hangout."
"I'm glad we could create such great memories together. Let's make more in the future!"
"Your company always brings joy and fun. Thanks for the wonderful time."
"You made the day/night special. Thanks for being a part of it."
Remember to be genuine and authentic in your response. If you also had a great time, express it sincerely. If you didn't enjoy the time as much, you can still appreciate their sentiment and respond positively, saying something like, "I'm glad you had a great time. I enjoyed getting to know you better." This way, you acknowledge their feelings without making any false statements.
