Your letter is not about your ex being a d*ck. If he were a d*ck, you would have stopped thinking about him by now. But you are thinking about him. Almost a year later, and you're reaching out to me, too. You said you shouldn't be thinking about him though. Has someone told you that? Often our friends do.
Just small samples at first, until I get you hooked on the power of it. You jones for the moment you can use your no on someone or something. Then that moment happens. Someone asks for something you are just not feeling like giving right then. And no takes over and it spills out of you. Elation and joy ensues. You are hooked and I'm on to the next corner of yessers.
Had I been able to discuss this decision with my closest friend when she could still discuss such matters with me, I think that Clare would have said that I should do whatever "feels right" to me. This decision to keep on writing about Alzheimer's issues, at least for the next few months, feels right to me.
