It’s raining as I write this. It’s Monday morning. The last time I sat at my desk, on Friday afternoon, it was raining. The weekend was mostly a blessed break — but tomorrow, when this is published and appears in your mailbox, the forecast says it will once again be raining. I’m fed up with the rain. I know that complaining about spring precipitation in Pittsburgh is as tired a gripe as bemoaning the Pirates’ low payroll. But I just wrote a column about that, too, so here we are: It’s rainy, and I don’t like it.
