And the mome rath Tavrobel outgrabe:
Have you just ever been in some situation where you felt like you needed help? Who care the subject, math, science, love? Have you ever tried to remember something, and it's on the tip of your tongue, but it just won't ever get out?
Well, my friend, that's called short-term/long-term memory failure, where your brain tells you that there's the information, but you just can't retrieve it. Fortunately we live in the real world, where there's just that someone, someone else that knows exactly what you're thinking. Thank God for that dude.
