The friend who keeps a simple promise gives you something ordinary and sturdy to trust.

Trust is built out of unremarkable evidence. Nobody decides to rely on a person because of a grand gesture. They decide slowly, on the basis of a lift that arrived at the time stated and a message answered when it said it would be. Those events are so small that neither party notices them accumulating, and their absence registers only as a vague sense that someone is hard to plan around.

Be careful with the tiny promises you make this week, and keep them exactly. Then notice who does the same for you, and let that count for more than charm.
