Well, maybe if you'd stop being a sententious gimmick windbag, he'd oblige. 
Nowadays, "sententious" is usually uncomplimentary, implying banality, oversimplification, and excessive moralizing. But that hasn't always been the case, nor is it universally so even now. The original Middle English sense of "sententious" was "full of meaning," a meaning adopted from Latin "sententiosus" (from "sententia," meaning "sentence" or "maxim"). In Modern English, too, "sententious" has sometimes referred to what is full of significance and expressed tersely. Or sometimes "sententious" simply suggests an affinity for aphorisms, as when it refers to the likes of Benjamin Franklin's Poor Richard (of almanac fame), the homespun philosopher given to such statements as "early to bed and early to rise, makes a man healthy, wealthy, and wise."
