Trillion. Hm. Trillion.

Do you know how much a trillion is?

Neither do I, really. I mean, I know it's a million million, which is a lot. But I can't picture it.

A million million. It's impossible to wrap your mind around a number like that. Trillion. It's not even a number, really - just a sound. But people throw it around all the time anyway, like they know what they're talking about.
