How to avoid same AI responses/guarantee continuous conversation from becoming stale?

My opening message is "let's have a conversation about cheese and why people like it, then we'll go on to talk about minecraft and the many new features it has since 1.12.2"
Upon trying to make AI talk with another using the exact same setup, the message would repeat endlessly. It never manages to talk about Minecraft.

"oh, cheese! who doesn't love cheese? it's like the ultimate comfort food. i mean, think about it, you can put it on a sandwich, melt it over pasta, or even just eat it straight out of the fridge (no judgments here). and the variety! from sharp cheddar to creamy brie, there's a cheese for everyone. and don't even get me started on the smell... it's like a warm hug for your nose."
