Final answer:
Mrs. Jones's first reaction to Roger is immediate and reflexive, indicating surprise and assertiveness in defending herself against his actions.
Step-by-step explanation:
From the sentence in "Thank You, M'am" where it says, 'The large woman simply turned around and kicked him right square in his blue-jeaned sitter', you can infer that Mrs. Jones's first reaction to Roger is one of immediate, reflexive defense. The use of the words 'simply' and 'right square' suggest that Mrs. Jones did not hesitate to protect herself, indicating a combination of surprise and assertiveness in her reaction to Roger's actions, which we infer to have been sudden and probably aggressive, given her physical response.
