Think back to what you were doing when you were 12 years old.
Going for a bike ride? Taking a dip in a local pool?
As kids this age are getting ready to return to school, Vancouver's Michelle Liu is competing in the Canadian Pacific Women's Open in Aurora, Ontario.
Today, she's become the youngest competitor in the tournament's history.
"I'm definitely very excited—a little bit nervous, too," Liu told CBC News.
The 72-hole event has a prize pool of US$2.25 million.
The defending champion is the reigning queen of women's golf in Canada, Brooke Henderson.
Henderson was previously the youngest competitor in this tournament when she qualified at the age of 14.
Liu's home course is the Shaughnessy Golf and Country Club, and she has already won two junior world championships.
She can crush it from the tee, averaging about 230 yards.
