In your "clever" attempt at irony, you ask your parent about his own, presumably better talks. Please take a moment to reflect on how utterly stupid this line of attack is!
Give up? OK, here's the explanation, by analogy: I'm completely incapable of building an automobile. Yet, having driven both, I'm qualified to comment that a Geo Prizm is an underpowered, shoddily constructed car - at least when compared to my Lexus. A talk is a product created for the benefit of an audience, and as the consumers of such a service, the audience - including the GP - is probably best qualified to judge it. To imply that only a producer of talks may have an opinion on a talk is shockingly stupid.
Before you attempt another such put-down, please consider how it will reflect on you, and whether it might not be more sensible to keep your mouth shut!
