I generally am a man of few words, largely due to my limited vocabulary! 🙂
And even so I normally manage to communicate fairly well.
(Though I resort to gestures most of the times, if not everytime)

That said, there’s something that pretty much gets onto my nerves.
Overly ornate language!
Yes siree.. The use of bombastic language in verbal communication!!
Perhaps, I’d appreciate it in written works. But oral communication??
And no sir, preparing for GRE is no excuse.
