I have noticed how often I -- and my female friends -- apologize for things that are out of our control. This, of course, is different than saying, "I am sorry for being late," or "I'm sorry I picked a fight last night because I was really hungry and you were taking forever to figure out our plans."
I'm always going to be scared; of failure, of disappointment, of not being good enough. But I'm done pretending that I won't feel pain if I'm careful enough, or that I can prevent the pain of others by just wishing hard enough. Saying I'm sorry is a verbal tightrope act, and it's one that I'm done performing.
