'Oh.' A pang of guilt caused her to look intently at her drink, 'That.' Of course her classmates might have thought... She'd known, what they would think, but Angela had never actually thought about it. About what effect her actions might have had on other people. If she wanted to, she could have found a multitude of excuses: She was 17, it was easier/better/safer not to tell anybody, they would have dissuaded her...
But ultimately she felt as though they weren't excuses at all.
In a rare moment of honesty, Angela's own discomfort mirrored Gilbert's as she shifted awkwardly, "Not very long. A day or two."
"I am pleased to see you." She admitted in a moment of sentimentality . Of all the people she could have run into, Gilbert was one of the more benign. And she was glad her classmate was alright.
