An ordinary favor completed well can become the beginning of practical trust.

Trust is built from small completed things rather than from declarations. Somebody says they will collect a parcel and they do, on the day, without needing a reminder, and something shifts: you now know what their word is worth in a way no conversation could establish. Reliability compounds quietly out of unremarkable evidence. Large trust is usually a stack of small tests nobody announced.

Do the next small thing you agreed to exactly as promised, especially when it seems too minor to matter. To know somebody better, ask for something modest and watch what happens.
