Interesting article! I have a guitar student who is about 8 years old and just a total pathological liar. He comes in and spouts lies like "my little brother has $700,000 and a PS5, and I'm going to go compete in the world cup this year" for about a half hour straight every time I see him. It's pretty hilarious but I wonder what his home life is like in regards to this, It seems to me like he just hasn't learned that there are any consequences for lying yet.
