I have times when I am less tolerant than others. I used to blame everyone else for these distempers, but now I am realizing that the issue is not really in them, it's in me. Perhaps I am hungry, or tired, or particularly hormonal. Maybe I need quiet time, or silliness, or to take a walk with the dog.
My moods are my business and my responsibility, and it's not up to others to keep me happy, or make sure all of my needs are met. It is not my place to spew judgment and negativity all over anyone. It is my place, when I have nothing nice to say, to say nothing at all.
I take ownership of my moodiness and don't make it anyone else's problem.
