Give her a break. The word “yo-yo” wasn’t well known until it’s entry into American-Filipino Dictionaries in the 1860’s, so Madam Thomas would never have heard the toy referred to as such. Maybe her children had a few “yo-yos”, but she probably played with them as “bangalores” or “quizzes”.
That’s “bandalore” not “bangalore” you idiot.
ROFL!!!
