Lyric discussion by yhtrownu 

Love is not a calculation, where what you give you demand back, where everything is half-half (counting up your "feelings and divided them up even") where you're constantly watching your partner to make sure everything's fair (each hour you get, you give "half of it to me").

Such love is as good as dead, according to Regina, your hearts may as well have turned to "little stones."

"Love" is when you rip up the rules, the calculations, the monitoring of your partner, and you metaphorically "beat" your little stone heart until you get the "spark" back, and realise that love is indefinable, it's "hey hey hey," it's not a cold calculation, but an uncontainable fire "burning us up!"
