So the flirtation went on all summer, like a ship under full sail, with prosperous breezes; and Mara, in the many hours that her two best friends were together, tried heroically to persuade herself that she was not unhappy. She said to herself constantly that she never had loved Moses other than as a brother, and repeated and dwelt upon the fact to her own mind with a pertinacity which might have led her to suspect the reality of the fact, had she had experience enough to look closer. True, it was rather lonely, she said, but that she was used to,--she always had been and always should be. Nobody would ever love her in return as she loved; which sentence she did not analyze very closely, or she might have remembered Mr. Adams and one or two others, who had professed more for her than she had found herself able to return. That general proposition about nobody is commonly found, if sifted to the bottom, to have specific relation to somebody whose name never appears in the record. Nobody could have conjectured from Mara's calm, gentle cheerfulness of demeanor, that any sorrow lay at the bottom of her heart; she would not have owned it to herself. There are griefs which grow with years, which have no marked beginnings,--no especial dates; they are not events, but slow perceptions of disappointment, which bear down on the heart with a constant and equable pressure like the weight of the atmosphere, and these things are never named or counted in words among life's sorrows; yet through them, as through an unsuspected inward wound, life, energy, and vigor slowly bleed away, and the persons, never owning even to themselves the weight of the pressure,--standing, to all appearance, fair and cheerful, are still undermined with a secret wear of this inner current, and ready to fall with the first external pressure. There are persons often brought into near contact by the relations of life, and bound to each other by a love so close, that they are perfectly indispensable to each other, who yet act upon each other as a file upon a diamond, by a slow and gradual friction, the pain of which is so equable, so constantly diffused through life, as scarcely ever at any time to force itself upon the mind as a reality.
