In the post, I said I had emailed Mark that morning, but the truth is that I had emailed Mark and written the post several months earlier, before I even started my blog. Anyway, I sent him a note, he responded after several days, and for some reason it took me about two months to write him back. I didn't hear from him again after that. I was sorry about it, but we hadn't been in touch for a long time and I figured we just had too little in common anymore to pick up a friendship.
But then this morning, I got another email from Mark. I answered it immediately.
Thanks, Mark. You made my day.
