You're on your point! There will always be people who don't care about what you talking, but not all are the same which is great, actually.
It's about patience and to listen what are people talking around you. Don't live in virtual world of smartphones etc. Listen to people and talk to people, those who disagree with you... respect their opinions too. It's on us to make Earth a better place to live. Have a nice day - @tonac :D
