All in resentment

If you ever happen to go through a season of dramatic change, some people will simply refuse to take you seriously. They'll dismiss you, talk down to you, or otherwise treat you as though you've changed flippantly. Often, they will explain their perspective to you, as though the only reason you now disagree with it is that you don't understand it. When you change, people will quickly forget that you used to hold to the same views they still hold to.
