Penny Oleksiak had some choice words for a high school teacher.

While not quite reaching gold medal status, Canadian Olympic swimmer Penny Oleksiak has done fairly well for herself at the Tokyo Olympics, bringing in two bronzes and a silver for herself and her country. To be more specific, she got silver in the 4×100-meter freestyle relay, and bronze in the 200-meter freestyle and 4×100-meter medley relay. On top of the previous seven medals she’s earned over the course of her career, it’s no exaggeration to say that Oleksiak is one of Canada’s premier Olympians, a fact she couldn’t help but broadcast to her old high school teacher on her personal Twitter.

“I just googled ‘Canada’s most decorated Olympian’ and my name came up,” Oleksiak wrote.

“I want to thank that teacher in high school who told me to stop swimming to focus on school bc swimming wouldn’t get me anywhere,” she added. “This is what dreams are made of.”

Oleksiak clarified in a follow-up tweet that she meant no disrespect to teaching as a profession, and that the majority of her high school teachers were very supportive of her athletic pursuits.

“Most of my teachers saw the vision and pushed me towards it,” Oleksiak wrote. “That one who constantly dragged me down though, WOAT.”
