After winning their second-round French Open doubles match in straight sets today, Venus and Serena Williams, who laugh and joke during most of their matches together, were asked what it’s like to play on the same side of the net. For someone talking about her and her sister’s sheer domination in the sport, Serena had a surprisingly casual response.

“It’s fun, we really help strategize, and we actually love playing doubles,” Serena said. “We have—I don’t know how many Grand Slam doubles titles—12, 13? I don’t know. Anyway, we still have fun. And it counts for us.”

It’s 14. They have 14 Grand Slam doubles titles.
