And I used my own gas to take Sam to practice Wed, but no worries about that.\"\n\nNotes:\n- Venmo is fine for her.\n- Sam's practice moved to Thursdays starting next week.\n- Grandma is covering Monday next week, so Julia's off.\n- She asked about a raise in January. Talk with Chris.\n- Julia has been with us since September; the kids love her.\n- We agreed on the late-night rate when she started, since she drives home late.\n- I usually pay Sunday night so she has it by Monday.\n- Leo had a playdate Wednesday, so she had both kids plus a friend for an hour.","rules":[{"type":"numberedItems","count":3},{"type":"plainText"},{"type":"maxWords","max":80}],"mistakes":[{"title":"Not giving the late rate","why":"The AI pays all of Friday at $18.","fix":"Add: \"Hours after 9 pm are $20.\"","checks":["r1"]},{"title":"Forgetting the receipt","why":"The AI pays hours only.","fix":"Add: \"Add receipts she paid for the kids.\"","checks":["r2"]},{"title":"Not asking to see the work","why":"A bare total is hard to double-check.","fix":"Add a line to copy: \"3.
