My 6 yr old came home with a girls number. This is the 3rd year they’ve been in the same class together. The first year they didn’t get along. He scratched her and I made him write an apology card to her. This year she gave him her number. The teacher told him to throw it in the trash so she slipped it in his bookbag 😂😂.
