hollllyyyyy, grandma is back
yea, thats a japanese thing, the first born of the gender is called the eldest son/daguhterI don't know if it is a quirk of the language, but Spica being described as the "eldest daughter" while her brother being described as the "eldest son" implies there are more siblings, to me?
so in a family of 6 with 4 kids (3 boy and 1 girl)
