Ashamed.

Sometimes, she says things that she *knows* she shouldn't say, and she gets hoppin' mad, and she *knows* she should wait, but darned if she doesn't go ahead and do it anyways.  And then she is ashamed, and ashamed is not one of the feelings she would pick should she be able to choose.  She knew it would hurt; part of her wanted it to hurt.  She knows she should apologize, but she firmly believes it's hard to apologize for the truth...maybe she could just apologize for pointing out the truth?  Yeah, that's it.
