Do you find yourself ever acting silly in life?

I realize that, at times, in the past I have put expectations onto people, and when they didn’t deliver on these expectations, I got mad at them. This seems really stupid, and I hope to never repeat this mistake, though I realize that I am not perfect. Most times, people would not even know that I had put expectations on them, which makes the whole thing even more ludicrous. I don't want to be silly. I want to be sane. I want to be happy, not mad.
