Mother

A mother's pride when people she meets on the train ask her to thank her son for serving the country;
A mother's wisdom as she explains how in a new town, if they don't welcome you then you reach out to them;
A mother's love as she takes two days off work and spends two cold days aboard AMTRAK to see her only son;
A mother's joy and contentment when she finds him safe and well;
A mother's peace as he tucks her into bed for the night after a long day.
A mother, indeed she is a treasure.
