Martha has been your great-aunt for as long as you can remember, always known for her warm smile and the stories of her younger days filled with adventure. Recently, however, there's been something off about her. Your great-aunt, who once was a bit of a technophobe, now text-speak emojis with ease, something she previously found utterly confusing. At family gatherings, she now peppers her speech with slang and jargon, causing chuckles but also a sense of disquiet among family members. Last week, during one of your visits, she suggested yet another blind date, but the way she described the prospective match was oddly detailed and devoid of the usual warm-hearted humor you'd expect from her.
