I (actually we both my wife and myself) learned quite a bit from our daughters’ teachers. A few months ago Serenity does not like to leave when we picked her up in the late afternoon. I recall one evening we were the last car to leave the parking lot
One evening, she said she wants to get a drink (water). Thought it’s a benign request, I took her back to classroom. She used 3 cups, obviously did not finish them all. I did not thought too much that day (evening) as eventually she leaves with me. Another evening, she’s doing the same in the classroom, and would not leave. Luckily the teacher was there, and talked to her about “just use one cup”, at that time I realized who is doing the dishes, not my mom, not me, not my wife, it’s our teachers
We should teach our child to be respectful of others. Another example is in the restaurant, initially I did not what to say when my daughter makes large noise, after a while I came up with this answer: we are here as guests, we should be respectful of other guests (not making noises). This is better than “don’t do that”. From negative to positive.
