Final answer:
The question appears to be based on the story of Michael Oher from the movie 'The Blind Side' and not related to the provided text from 'McTeague'. However, Sean Tuohy helped Michael understand Leigh Anne by bridging communication and cultural gaps, fostering a family bond.
Step-by-step explanation:
The question seems to misplace the context and may be referring to the story of Michael Oher, as told in the movie The Blind Side, where Sean Tuohy and Leigh Anne Tuohy help Michael Oher, a homeless and traumatized boy, become an All-American football player and first-round NFL draft pick. In the film and book, Sean Tuohy played a pivotal role in helping Michael Oher understand not only the game of football but also the family dynamics, in particular, understanding Leigh Anne Tuohy, his adoptive mother.
There isn't a direct reference to this event in the quoted text from Frank Norris's novel McTeague. The context provided appears to be a separate work of literature that does not relate to Michael Oher's story. In any case, by providing a stable home environment and consistent support, Sean Tuohy was able to bridge the communication and cultural gaps between Michael and Leigh Anne, fostering a mutual understanding and strong family bond.
