Apparently she was wrong in her thinking that whoever it was would not bother her. She didn't have any problems with James, but she was still simply not ready to talk about what happened.
She forced a smirk on her face when she replied back to his words. "Aw," she said playfully touching her chest around her heart, "Did ya miss me?" This was her way of dealing with things around other people. She would be by herself while she could, and when that wasn't possible she would be sarcastic. "Maybe we could paint our nails later to bond."
She continued her smirk at him so that he would know she was simply teasing, but her hands returned to the piano where she began playing an Aerosmith song. "Just lost track of time I guess," she answered his question a bit more serious. It was a true enough statement. She likely wouldn't get into the real reason easily.
[ooc: I am so disappointed in you, says the person who took forever to reply lol]
