Read it through once

When Amy and Laurie wrote of their engagement, Mrs. March feared that Jo would find it difficult to rejoice over it, but her fears were soon set at rest; for, though Jo looked grave at first, she took it very quietly, and was full of hopes and plans for "the children" before she read the letter twice. It was a sort of written duet, wherein each glorified the other in lover-like fashion, very pleasant to read and satisfactory to think of, for no one had any objection to make.
