A short ride for one person can be the manageable part of another person’s long journey.

The same distance means different things depending on what surrounds it. Twenty minutes in a car is nothing to the person driving and may be the only feasible section of a day that also involves two buses, a wait, and a walk somebody’s knees will complain about. Offering to cover that section is a much larger favour than its cost to you suggests. Most useful help works like this: small at one end, structural at the other.

Ask what part of the journey is hardest rather than whether someone needs a lift. Then take that part, and do not make a thing of it.
