People will strongly disagree with what you believe is the flat out truth. As frustrating as it can be, people will not always be accepting of criticism and advice because it may force them to perceive situations or experiences that are not “normal”. People will get offended by the truth because society has trained their brains to limit their thinking capabilities,even if they may not realize it. Having expectations for those around you is okay, but everyone learns at their own pace and all you can do is to be a living example of your own beliefs to prove that point.
