Reddit Stories | OP's birthday is approaching. A surprise birthday dinner for his twin brother is being organized by one of his close friends, and he has been invited as a guest. However, he feels hurt and disregarded since the dinner seems to focus solely on his brother's birthday, even though it's also his own birthday. He believes it's inconsiderate and upsetting to be invited as a guest to his own twin brother's birthday celebration. His girlfriend shares this sentiment and wonders why the event wasn't organized to include both twins or coordinated with her to make it a joint surprise. OP is torn between attending to avoid feeling left out, as their mutual friends are going, and not attending to stand up against what he perceives as disrespect and unequal treatment. He seeks advice on whether refusing to go would make him the "asshole" in this situation.
