Don’t be so surprised. Playing video games with violence content is the worse. Games like shooters especially. I saw so many times kids that were swearing so hard because they died in a game. I was amazed how they could even know those words. It was nothing to them, they were full of anger and uncontrolled emotional behavior. If parents will ask them to shut down their games, they answered in the same way. Crying, beating and damaging stuff around them. Kids are like sponges and if they absorb such emotions, nothing good will happen as they will grow up. Silenced, isolated and full of hatred. So many cases are present in our days. You can see videos on YouTube, a lot of them. Grown-ups easily are spotted, but they try to hide their anger from the guests or people that surrounds them in public places. I had a friend who liked gaming but had these type of side effects, and I introduced something special to him called red bali kratom, now he plays calmly and when he loses, he laughs! It works like doctors prescription.
