I can’t speak for others but as an older millennial, I grew up liking spending time on the phone with friends and loved ones. However in my adult life, I spent being anxious waiting for phone calls regarding job interviews and outcomes of them, and even being interviewed on some of them, including those without much notice. I also had to make calls to follow up things urgently or if I’m in trouble. As a result, I started to equate phone calls as mostly negative experiences.
