"Faulty grammar" 

The fault, dear Chunk, lies not in the stars but in your edits. "was offered to play" is grammatically wrong. "utilized yoga classes he had been taking regardless of the series" is tortured construction. Words that end in "s" take the plural with an apostrophe-s, not a bare apostrophe. If you're going to "correct" grammar, please use correct grammar while doing it. Thanks ever so.
