Sia - Academia

You can be my alphabet and I will be your calculator
And together we'll work out on the escalator
I will time you as you run up the down
And you'll measure my footsteps as I pleasure this town
The mean of our heights is divided by the nights
Which is times'd by the daggers and the route of all our fights
The pass of your poem is to swathe me in your knowing
And the beauty of the word is that you don't have to show itOh academia you can't pick me up
Soothe me with your words when I need your love
