>>Why does she feel the need to tell everyone about her decision to have sex in a Chevy Vega?<<
Quite an acrobatic feat so why not brag?
While sex in a Vega is impressive, I’d be more impressed if she changed the spark plugs on a V8-powered Vega...
Yep.
Monday morning in high school the guys would be bragging to each other about how they went Vegan with some girl in their Chevy on Saturday night.
