But love is much like a dam: if you allow a tiny crack to form through which only a trickle of water can pass, that trickle will quickly bring down the whole structure, and soon no one will be able to control the force of the current. For when those walls come down, then love takes over, and it no longer matters what is possible or impossible; it doesn't even matter whether we can keep the loved one at our side. To love is to lose control.
