Crazy colors in their hair
What is something that is really popular now, but in 10 years everyone will look back and be embarrassed by?
I guess cellphones.
The way these young "adults" act! They think its popular now but in ten years when they have seen what it's like in the real world... All their attitudes and "triggered" safe spaces will be obsolete when reality hits them hard.
Trump as president...?
Level of maturity.
