Sometimes it doesn't matter how many times we proofread. We still make mistakes and don't spot them because our brains automatically correct words that are close to being spelled correctly.
When I was a newspaper reporter, we received dozens of complaints from readers if we had a single misspelled word. Callers would tell us how stupid we were. They'd laugh at us. They'd shout at us. I once said to a colleague, We get thousands of words right every day, but we make one little mistake and people go crazy.
I once wrote manger instead of manager in a graph on the front page. I checked the graph several times. An editor checked it. The graphic artists checked it. Manger still still got past us.
At least I didn't work at the newspaper that made this error:
Keep proofreading! We can't give up even if a mistake gets past us every now and then.
And let's not "shits to Boston."
Infinities of love,
