It’s a warm, sunny day and here I am, stuck inside, slitting open envelopes and finding letters like this. Not that I don’t appreciate your sense of humor. I know you probably need an outlet and that writing letters like this to guys like me is probably all that keeps you from becoming a serial killer. Still, one is left rather adrift in terms of how to respond. Then again, my alternative is to keep going through the stack, possibly finding even dumber letters (here’s a candidate: “This summer I’m taking the family on vacation to Rwanda and Uganda. There’s just one thing that’s bothering me–what happens when I leave Rwanda, where they drive on the right, and enter Uganda, where they drive on the left?”), or worse, a letter that will actually require me to get on the horn and do some work. So let’s take a crack at your question.
