Is this a good and proper sentence? [closed]
It depends on what the author believes is "a good and proper sentence." If it means that the sentence is grammatically correct, then the sentence is good and proper. If it means that it is both grammatically correct and sensical to a developed human being, then it is not good and proper. Then again, the word "good" is subjective - so in the end, it is up to the author to decide.
