Someone posted this from an article the other day. These words are so true. I've learned over the years that when someone decides they hate me for no apparent reason, I just let it go. There's no arguing logically with a crazy person. I've tried, and it never helps the situation. The best bet is to let it blow over, and if it doesn't, did I really want them in my life? And did I really want the people they influence to join them in hating me in my life? Probably not.
I think this is part of my "shrug it off" attitude to most things. Work-related politics, things I can't control, someone who judges me for not having kids....I just shrug it off.
I am pretty happy in my current life, and I've realized that I am very happy when I don't let other people's opinions undermine my own.
