From 8-year old Hilda’s diary:

Suzanne was here for lunch today but didn’t stay very long, because she had to go to a ballet rehearsal and all she could eat was a little sandwich with a cup of tea. She said it was because she had to dance right afterwards. I can always eat a big lunch before I go to my dancing school class.

Unfortunately, I have been unable to find any newspaper articles about the ballet in which Suzanne performed in San Francisco in March 1912.
