small typo

[gumbol]

chapter 6 the beginning of the paragraph just above the Symbols section.

"And we can also add this interface to your own objects! But before we can do that, we need to know what symbols are."

replace "and we" with "and you"

Thanks for pointing that out. I think it works better when changing 'your' to 'our', as in attached patch.
