DD7 made her very first complaint to her teacher today! I'm partly proud and surprised, partly apprehensive and not at all surprised. Very complex reactions as you can see, lol!
DD loves school, is happy to comply, loves following rules, loves the routines, the friendships, works hard, engages fully and is super polite - but if she's anything like her brother, this will start to go sour by about age 9-10. I can see it coming. Right now she's a teacher's dream. In a few years, very few of them will understand her. A couple of them will LOVE everything she says and is. The rest will think she's off-topic, odd-ball, unfocused, too difficult.
Her teacher this year (the year starts in February here) is awesome and completely took her complaint on board and is doing his best against the school policy of "if we give her xyz now, we'll run out of things to teach her." With a less-interested teacher things will go sour faster.
Luckily this time, fingers-crossed, we're forewarned and forearmed. Last time we had noooo idea what had hit us smile
