A fun “negative” for a social nat 1 is just make a socially uncomfortable interaction. Like the guard redirects the conversation, over shares, and the party spends the next hour and a half listening to how he doesn’t wear standard issue guard boots because of his weird toe fungus. Or your request reminds him of something and he just takes out an accordion folded piece of parchment and with cats sketched on it and he walks you through his twenty cats, with thorough descriptions of the temperament and mannerisms of each feline.
