I never was a socialist, always of right wing. So how you can see emotions and political parties not always are correlated to certain things.
What should i miss of my 20s? Maybe the fact of not having properly love by a girl. For the rest I'm ok, look around you, these youths do drugs, they go drunk, they do bad things to girls, they betray even their parents. If being youth means this, then no, I love to be one of the few exceptions of this generation, also you're right, they will never listen to you, cause nowadays mostly adults are always like "oh come they're just teens or young adults, it's normal"
