GfS, if I missed the context (which I didn't. I did manage to puzzle out what you were attempting to say), it would have been because you expressed it so awkwardly. Rather than "more stupider," it would have been correct to say "even stupider." That conveys what you were groping for without making you appear illiterate.

No need to thank me.

Sorry, I don't have time to play right now. Guests.
