In English, when I say don't fool around with that, am I saying You are stupid!
I mean, my son came back from school today with a note from the teacher:
I was fooling around with a paper today and I go my clip moved. I was suppose to be paying attention to the teacher's lesson. 3 times she told me to stop fooling around and to put my hands on the table but I didn't. I'm sorry that I was fooling around in class.
How do I explain this phrase to my son:
Basically your teacher said you are stupid. That it is stupid to get distracted and play with a paper. While your teacher gives a lesson in front of class. That is what a stupid person would do. Don't do that again or she is going to think you really are stupid.
English is my second language so, before I tell my kid, Yea that was stupid to do! How do you explain that phrase?
