At the end of our conference the teacher suddenly told me this:
Teacher: G told me that her middle name 'Genesis' is named after her sister.
Me: Yes. Her big sister.
Teacher: That's a beautiful name
At this pint G and D2 were being fussy and the conversation didn't continue but she knows D as he used to be in her class too and she has seen me bring in D2 all the time. I'm not sure if she knows the story behind Genesis. G doesn't recall if she told her or not. But I'm glad it didn't put me in an awkward conversation.
In other news G just told D that she doesn't like it when D forgets Genesis. At times he forgets to draw her in our family pictures. D says he promises to never forget. I hope so.
