From 8-year old Hilda’s diary:

Grandmother told me this morning that I would have to start piano lessons again and I hate them. I hate my teacher but I have to have her, because her mother is in an insane asylum.

Although she says she hated piano lessons, in earlier diary entries, it is clear that Hilda loved music. In fact, she became quite an accomplished musician, as can be seen in this newspaper article from the San Francisco Chronicle from February 25, 1925 when Hilda was was 21 years old.
