She had walked with her friend to the top of the wide steps of the Museum, those that descended from the galleries of painting, and then, after the young man had left her, smiling, looking back, waving all gayly and expressively his hat and stick, had watched him, smiling too, but with a different intensity--had kept him in sight till he passed out of the great door. She might have been waiting to see if he would turn there for a last demonstration; which was exactly what he did, renewing his cordial gesture and with his look of glad devotion, the radiance of his young face, reaching her across the great space, as she felt, in undiminished truth. Yes, so she could feel, and she remained a minute even after he was gone; she gazed at the empty air as if he had filled it still, asking herself what more she wanted and what, if it didn't signify glad devotion, his whole air could have represented.
She was at present so anxious that she could wonder if he stepped and smiled like that for mere relief at separation; yet if he desired in that degree to break the spell and escape the danger why did he keep coming back to her, and why, for that matter, had she felt safe a moment before in letting him go? She felt safe, felt almost reckless--that was the proof--so long as he was with her; but the chill came as soon as he had gone, when she took the measure, instantly, of all she yet missed. She might now have been taking it afresh, by the testimony of her charming clouded eyes and of the rigor that had already replaced her beautiful play of expression. Her radiance, for the minute, had "carried" as far as his, travelling on the light wings of her brilliant prettiness--he, on his side, not being facially handsome, but only sensitive, clean and eager. Then, with its extinction, the sustaining wings dropped and hung.
