How to say your welcome without saying you're welcome?

I'm intrigued by the idea of expressing gratitude without using the conventional phrase "you're welcome." Could you elaborate on some creative and thoughtful ways to acknowledge someone's appreciation? For instance, how can one respond to "thank you" in a manner that conveys warmth, sincerity, and perhaps even a deeper connection? Are there any cultural nuances or universal expressions that you've found to be particularly effective? I'm eager to learn more about this subtle yet meaningful aspect of communication.
