Thea and I work on her letters at least two or three times a week. In that time, I've learned that Thea learns very quickly. I've also learned that Thea will show you what she's learned, if she feels like it, and doesn't really mind if that is fist-shakingly frustrating. Sometimes Thea will know exactly what you want her to show you, know how to do it perfectly, and give zero fucks about just not wanting to do it. If she weren't so sweet about it, I think we might have given up a while back.
