I also promise to fail
I promise to lose focus, to be late
I promise there will be times
when I need to unplug from the world
I know it will happen
and none of it will lessen
all the care I have
and always want to have for you

I hope to have your hand close by
holding me the times I stumble
showing me you believe in us
that you understand

we don’t always manage to express

something so immense
without it getting tangled

We need to be permeable
to each other’s needs and desires
so the light can gather
and expand us into ecstasy

It is in those highs and lows
of closeness and distance
when we fall apart and rebuild ourselves

aware of what truly matters
that I want to give you the best of me
alive, and unafraid to lose all for you
to be permeable is to see your light and let it in

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
