That isn't foolish. If it isn't quantified and is written in overly vague sentences, what choice is there but to assume what the sentence meant?

English Clinic 101:

"The soccer balls are round. The golf balls are white."

That means all soccer balls for a specified location/time/place/whatever are round. Same with the golf balls. That is what "the" does.

What's more foolish than my assumption? His lack of grammar.

Back on topic.
