i know someone like this...

Since light travels faster than sound, people appear bright until you hear them speak.

seriously i do. what a know it all... just because you use those big words you see in books doesn't equate to you having a higher IQ. it would even be great if you understand half of what you're saying and know what they mean when you use them. sometimes, it's easier to express what you want to say in tagalog especially if it's just an informal conversation... don't make your nose bleed too much or even tire your brain...
