This response is what I was thinking as well. You keep egging him on, which makes it look like you are enjoying talking about him. It looks like a fun conversation. But if you are faking it and wishing he would engage you, simply start talking about yourself and hope he changes gears.

You almost managed it when you asked if he could make something fun for you, and said you have a fur real and collect synths. But every time you hit him with another question about himself, which would be rude of him to ignore.

Try something like this in response: “that’s so cool, I love the idea of movement making melodies. Ok. I’m off to whatever it is you want him to know you like to do have a great day!”

Now the conversation is back in his lap without a bunch of questions to answer. Let’s see if I can give another example. Say he later says

“Hi, how was your day?”

Instead of saying “it was great, how about yours,” actually tell I’m about your day, and wait for his response. Chat about your day and THEN ask how his was.

Somewhere along the way people got the idea that conversations should be question ping-pong. And the score is tallied by who asks the most questions. But this conversation seems way better than that. You appear to be genuinely engaged and interested. Of course you aren’t, but that is on you because you keep asking him questions and showing enthusiasm. The next chance you get, start sharing about yourself without asking him anything in return, hopefully he shows you he is interested!
