Division
Take a group of things and split them up into smaller things, a process kids have difficulty with, trying to teach long division with grade tens of polynomials and the difficulty they have with it, what's the point, hard to think of splitting things up, ummmmm, not sure what else to say, fractions, decimals, being separate from my family here in vancouver, divisions in politics, no one can agree, divisions in the church, humans need to be right create divisions, divisions in families when not everyone agrees exactly with each other, this is a very difficult exercise in and of itself, how does it relate to life outside school, how to reconcile deep divisions, have nothing else to say really about this, hate being divided from those I love, gonna happen again on Tuesday...
