because i was fated to listen to it.

my maths teacher was going on, and on, and on, about the current topic that we're learning, and i on the other hand, as always, was busy, daydreaming about you. but i was brought back to reality when his words caught me hanging, " in order to move on, you need to know the past topic very well first ". i know that he was talking about maths, but i wonder, can that work in real life? if it can, so fate wants me to move on, yes?
