I don't know which is the worst but I watched my nephew, who is generation z over the holiday and didn't like what I witnessed at all. He's a good kid overall but I felt he was very unappreciative. He got really expensive stuff and I didn't hear even one thank you, only who/what's next? Then he was ranking his gifts in their order of preference in front of the people who gave them to him and wasn't told that this is an inappropriate thing to do. He also sassed his mom and had to be given a time out. I'm not a parent so I can't tell if this is normal behaviour these days. All I know is that I would have got a smack for some of the things he was doing, so wouldn't have done them to begin with. He's also the product of a broken home so I suspect some overcompensation may be happening and that many excuses are being made for him. The lack of discipline has me worried. If he's like this at 10 what's he going to be like at 16?
