your kid is not wrong. it can be so hard to focus when looking at a screen vs in person in a class. my own experiences have shown me that. to this day, I can focus if i have a book in my hand and the world is busy around me. But I can not seem to ever focus on a story while at my computer. So many of you may read what I'm writing and go on to read everyone's stuff. I cant. I'll fall asleep. I'll read a short bit to get the gist of the subjects and move on to other things. ADD is real. I hope your kid gets the right kinds of inputs that will keep him focused and learning
