Have you met a millenial? Probably not. They're some of the most introverted folks around. They're not heeding warnings, because they don't have to; they're already sequestered in their childhood bedrooms.
Some are introverted, certainly not all.
A millennial sold me a new car in Feb...he sold 500 new Chevys last year.
That is not totally true. I know many millenials and there is not ONE “sequestered” in their parents’ homes. They are getting laid off and worried about paying for life. Do not know about the gathering part.
