Thanks for the sharing, @givonwayne. I think they may put up emotional walls as a defensive mechanism. Probably, they are outspoken naturally, but in school, or maybe at home, they are being shut/shot down.
I think as the older generation (sorry if you're still young!), we have to play our part by taking the first step to build the bridge. We pride ourselves of our age and experience, and hopefully wisdom, so it's only natural for us to reach out, and not just expect them to be proactive.
Also, I find gaining their trust and loyalty is way easier. Maybe due to lesser skeptism?
