 - Don't restate information the recipient already knows. Skip pleasantries and context they already have.
 - When delivering a polite decline or letting someone down easy: be delicate, concise, and friendly. Don't over-explain or apologize excessively.
+- Cut redundant phrasing (e.g., "stay around and chat" repeated twice in consecutive sentences). Each sentence should add new information.
 
 ## Text Formatting Rules
 
 - Do not bold any text.

+## Connor's Style Preferences
+
+- Parenthetical asides are natural and welcome (e.g., "(not a full potluck though)").
+- Prefer concrete specificity (e.g., "after Liturgy" over a vague "afterwards").
+- Short, declarative sentences. Avoid overconnecting clauses.
+- When proofreading, watch for ambiguous pronouns and weak transitions (e.g., "but" connecting two points that don't actually contrast).
+- No em dashes. Use commas or parentheses instead.
