Ew, people call you? All my friends text, because they know we are busy adults, I’ll get to the chat when I can get to the chat. Little monster stays on vibration only or complete silence until I decide so. I control the damn thing not the other way around. Everybody who knows me or I give my phone number knows that phone call means someone died, there’s blood everywhere, or the building got set on fire. Nothing else requires phone call level urgency.
Phone calls are for urgency and very often I do need to respond quickly. I also expect and am disappointed when people don’t answer calls from me because I only call for urgent matters.
Even if my father knew how to send text messages, his fat, dry fingers can’t use the on screen keyboard.
You’re still over estimating him. He grew up with leaded gas. He still goes out of his way to buy the stuff at airports.
