I don't think it is a big deal either. I typo all the time myself (like I said, 'black keyboard syndrome'), I only brought it up because the meaning (of fish meditating) was so darn cute.
The one thing that REALLY bothers me grammatically is the incredible misuse of the word 'there' (mixed up with 'their' or 'they're') and that is only a reflection on our education system (and the difficulty of this language).
"
They're going
there to pick up
their fish."
Oh...and the (NON)word: "irregardless"!
