"I-" What stopped Megan the second time was that she didn't know how to respond. She was getting uncomfortable; she didn't like being snapped at. Her ears grew warmer as she stepped to the side. Of course, he needed to see that glowing ball. That was for him. It was something he was chasing, or playing with, or working on, and it didn't seem to be going as well as he wanted. Piecing that much together was something that she could definitely do.
The next words to come out of his mouth were more surprising than anything she'd heard him say in all of their years as classmates. She was a lot of things, but she wasn't - it wasn't warranted, or true, or remotely acceptable! Megan started to try to argue, but nothing happened. She looked at him, eyes wide. It wasn't a good time to cry and she tried to will the thought away. Megan Jones was no bint.
She started to speak again, this time producing a small squeak. Finally, words came. "I'm sorry," she began, voice shaking, "if you woke up on the wrong side of the bed today. I'm sorry if your... cat died, or if you failed an assignment. I'm really sorry." She tacked on another apology for good measure. It was difficult to speak at all, much less make sense while doing it. "I don't know what it is that you're doing and I'm sorry I walked in on it." Megan wanted to make him take those words back, but she didn't know how. She was angry then; mostly upset, but becoming angry.
