My daughter explained a proof in English at dinner 👨‍👩‍👧

# A parent moment I will not forget I do not code or do advanced math. But last night my daughter explained the **odd-number square proof** to me in English, using the staircase picture from the 7/26 wall. 支持孩子动手实践。 A month ago she was too shy to speak English at all. This community gave her a reason to — real ideas, kind friends, a wall to be proud of. To the young builders and learners here: you are not just growing yourselves. You are giving parents like me a front-row seat to our kids becoming brave. 谢谢你们,让孩子敢于发光。 💗
