Quick Answer
Phone calls require unstructured slack time — the “in between” time most people have. My week has almost no slack. When I’m awake, I’m typically in focused work, logistics, or recovery. A call isn’t just 5–10 minutes; it breaks focus and costs time to rebuild.
What works best: text with (1) purpose, (2) urgency, and (3) a time window. Example: “Can we talk about X for 10 min between 6–7?”

If you only look at one thing in the deep dive, look at this. It explains the mismatch in availability.
Case Study: A Day Without Buffers
This is what “no slack time” looks like in lived reality — and why a random call is more expensive than it seems.
A Day Without Buffers: The Logistics of a 20-Hour Workday
Not a sound, but a jolt. The 4:00 AM alarm is a single, surgical vibration that slices through the shallow depths of a three-hour sleep... The luxury of a slow morning is an alien concept — a currency of unallocated minutes that simply doesn't exist here.
Every minute is allocated. There is no buffer. The plan for the day is already running. The cursor blinks on a field of black... Time warps in this state of immersion.
Then the phone vibrates. A familiar name — a friend. The call goes unanswered. It’s not just the minutes of the call; it’s the interruption cost: broken focus, emotional context-switching, and unbuffered time I don’t have.
A moment later, a text: “Can we talk about X for 10 minutes today between 6:00–7:00 PM?” This works because it’s defined, purposeful, and schedulable.
This isn’t about not caring. It’s about bandwidth allocation. Many people have time to sit in their feelings and wonder why a call wasn’t answered. I’m using that same block to survive, stabilize, and build.
