No one has my phone number, because if I were to give it out -- well, one, no one could keep it private. And two, they might call. And I don't want to talk to these people. The other day I made the mistake of emailing my mother, and now I get a dozen pointless and impersonal messages every time I check my account. So I've filtered her out so I don't have to see any of that.
Someone I know was appalled to learn I hadn't seen my parents in five years. What, I said, it's only five years. I certainly don't plan to see them again. If I were to, it would be under strange circumstances. Particularly my father.
I think my sister has some health problems. I'm not really interested. Someone else I know thinks it's a travesty that I don't have a relationship with my sister. I'm not sure I see the reasoning. I don't know her. So... why is that different from my not knowing Mick Jagger? I'm not interested in knowing him, either.
