Do Sammy's observations reveal his youth?

Sammy’s observations, such as "two crescents of white"
(paragraph 1), suggest his extensive experience as a "girl watcher." He has also watched
older women, as is indicated by his disparaging comments about some of the less
attractive physical characteristics of aging. His remarks reflect his taste for youth
and beauty, but also his own limited understanding of life as a boy of nineteen. His
estimation of female intelligence in paragraph 2 about a "buzz like a bee in a glass
jar" and his expressed lack of certainty about how girls’ minds work indicate, under the
guise of minimizing women, a lack of experience with women on an adult level. His
gesture to quit his job is at odds with his patronizing estimate of women, for it shows
more respect than he overtly expresses.
