I can learn from this

One thing this hands over reliably, and it isn't a lesson about yourself. It's an unusually accurate list of who does what under pressure. The person who kept turning up with food and never once asked how you were coping. The one who went quiet in week two.

That list is worth keeping and worth being gentle with. Some people go quiet out of cowardice and some out of having no idea what to say. Either way you now know something about your own life that was invisible six months ago, and it will shape how you spend the next ten years.
