<human>: I just remembered a time when I was in middle school and was getting into the Redwall Series by Brian Jacques. At my school library there were posters that said he was going to be at a local bookstore signing. For some reason, I didn't go. Thinking about it now, I feel upset about it. I had the chance to meet one of my favorite authors, and I didn't do it. And finding out that he died somewhat recently is even more of a bummer because I'll never meet him now.

Has anyone else had a moment in like this?

Can you condense the text into three sentences or less?
