Some folks can be reached. Some can have the fuse lit that leads them to look more critically. Some refuse to believe and think you are crazy, but when they start to hear it from other sources, they start to wonder. These people can be reached. The ones that want to physically assault you because you don't believe what they believe, these are the ones that you can't reach. I just smile and tell them to make sure they get their booster and two masks is a minimum. It reminds me of Noah, building an Ark. Folks all told him he was crazy, but he kept telling them the whole time. When the rain started, he had to watch as the doors were shut. All those that refused to believe were resigned to their fate and drowned. I pretty much feel like that sometimes. When you reach out your hand to rescue someone and they slap your hand away, you can't beat yourself up about it. You did the best you can.
