If I asked if she had said thank you after being at someone's house before we left
I had to ask her to repeat herself 4 times cos I couldn't tell whar she was saying. Turns out she was just making a noise, not actually saying anything.
In a bad mood for a fair bit after we left and that shows in her behaviour towards me and her rudeness.
Buying her some sticky rice later when out. But acted awful because she didn't have a drink to have with it. Immediately getting in a huff and a mood and storming off and slamming the table
Does your 12 yr old do this
