Okay, there was more than slight discomfort on Spoiler's part. Batgirl realized she'd probably shared too much, which was kind of confusing, really. As much as she'd observed people talk about and think about this particular subject (and more than once over the years, she'd observed the act itself), one would think there would be less embarrassment about discussing it.
"Sorry," was all Batgirl could think of to say.
She tilted her head to the side. "Yes," she replied, on the subject of girl talk. Of course she understood what they were doing right now: they were both girls, and they were talking.
