Have you ever realized you have completely misjudged someone?
I experienced this recently, and I could not feel much worse about doing so. For someone who has long felt misjudged or misunderstood, I too easily fell into judging someone else.
Notes to self: If someone seems different then they were, don't assume the worst. Don't jump to conclusions. Don't get your feelings hurt and get all defensive. Even worse, don't spread your judgy thoughts to others. Things may in reality be the complete opposite of what you think. That person may really need someone to notice subtle differences, for someone to really see them. They may try to reach out, and you need to be able to see that's what they're doing without all your assumed judgements clouding your eyes. You can be so wrong when you are sure you're so right. Get over yourself. Open your heart and eyes a little more.
