[D&D] dming a session and I've hit that perfect DM zen where I just gave my characters a bunch of info and they've been gnawing on it for about an hour

so I just get to sit here and listen

I've dropped them in a city with 10 different merchant families, one that wants them dead, another that has something they need, and the other 8 in varying degrees of helpful and not helpful

and they're trying to figure out how to pit these families against each other to get what they want without dying

half an hour later, they're still going /chefs kiss

Huhuhu

whispers they talked for the rest of the session

like. two hours. nonstop

actually three hours

now that I think on it

I honestly gave them like. maybe a half an hour of NPC interaction and exposition and they ran the rest of the session themselves
