Well, Bingley, I'm 26, and I understand "thoughtfully" to mean either "considerate" or "deep in thought", depending on context. But then again, I read too much.

As for "hubbub", it's another great word. I don't consider it comedic. But then again - I've already told you - I read too much. I might get strange looks if I used hubbub in normal conversation with my peers. (Mind you, there are plenty of words I do use which elicit strange looks from people.) Too bad for them!
