I can't think of one time where I have changed how I've thought, or how I've acted because of a post on a message board.
To be honest, I've always been a laid back, go with the flow type of person; and until reading message boards such as this one, I never realized how much other people analyzed and picked apart the actions of others.
While I was well aware that other people did things differently/raised kids differently/spent money differently/looked at politics differently/etc... than I did, I always just chalked that up to - we're all different people with different experiences, that have brought us to different places in our lives. Never in a million years did I suspect that some people considered me wrong/rude/tacky/offensive or whatever just because I didn't do things exactly the way they did. It has truly been an education.
People are all different, but the one thing we all have in common is we all just want to be accepted for who we are. And that's a fair enough request. I've always tried to accept people for exactly who they are - I'm amazed at their gifts, and share their sorrow as they deal with their challenges and just love them for who they are, warts and all. Sure, some people can be extra challenging - I just consider that the entertainment factor; but one thing I've learned by accepting people for exactly who they are, is that over time, as they get to know me, they do the same for me. And that is probably the best feeling in the world. Tolerance is a beautiful thing, isn't it?
