Final answer:
The underlined sentence suggests that Framton is self-conscious about his shyness.
Step-by-step explanation:
The underlined sentence in the excerpt suggests that Framton is slightly self-conscious about his shyness. The sentence states, 'Romance at short notice was her speciality', implying that Vera, the character speaking in the excerpt, is fully aware of Framton's nervousness. This indicates that Framton's shyness is a notable characteristic and possibly suggests his discomfort in unfamiliar social situations. The sentence does not provide evidence that Framton lacks courage or is easily irritated, but rather emphasizes his self-consciousness.
