The phrase comes from the Spanish version of Heidi, the 1974 Japanese anime series based on Johanna Spyri's 1881 novel about a girl living with her grandfather in the Swiss Alps. In Spain and Latin America the dubbed opening became inseparable from childhood television, with its opening question sung by a child voice. Decades later the line circulates online as a soundboard clip and meme audio, shared by adults who grew up watching reruns and now reuse it to mark innocence, family and nostalgia.
