"I have been waiting here for you--I mean for the person I am to meet--" Dorothy thought she had betrayed herself, and that John would surely recognize her.

"I had been waiting full five minutes before you arrived." John's blindness in failing to recognize Dorothy is past my understanding.
He explained it to me afterward by saying that his eagerness to see Dorothy, and his fear, nay almost certainty, that she could not come, coupled with the hope which Jennie Faxton had given him, had so completely occupied his mind that other subjects received but slight consideration.
"But I--I have been here before this night to meet--" "And I have been here to meet--quite as often as you, I hope," retorted Dorothy.
They say that love blinds a man.

It must also have deafened John, since he did not recognize his sweetheart's voice.
"It may be true that you have been here before this evening," retorted John, angrily; "but you shall not remain here now.

If you wish to save yourself trouble, leave at once.

If you stalk about in the forest, I will run you through and leave you for the crows to pick." "I have no intention of leaving, and if I were to do so you would regret it; by my beard, you would regret it," answered the girl, pleased to see John in his overbearing, commanding mood.
