redundant

You've got to love Mondays when you open your inbox to an e-mail sent by a reader so moved by your story that he sends a message at 8:26 a.m. Saturday to tell you you're redundant. With that subject line.

Yes, he was right. I slaughtered myself in the grammar department when I wrote "PIN number" instead of PIN.

But he also sent the same e-mail twice, which is redundant, isn't it? It took everything in my power not to point that out.
