So, you've completed your manuscript, proofread it, and if possible read it aloud to a friend or had them lend an editor's eye.... Your spelling and grammar program says there are no mistakes and you can't find anything out of the ordinary.
This is when you submit it, either by email or slow poke snail mail.... Then it happens... Your piece is printed and there are typos. You're horrified!
Well, whoever entered the content may have made a typo or two. Is it the end of the world? Sure, it makes us look bad but it could be worse somehow (use your imagination)....
Maybe it was our oversight.... We made a mistake (is that a sin?)
I say: "Let it go!" We're not perfect, editors aren't perfect, and whoever entered the content is not perfect. Forgive it, forget it, and move on.
