in case of emergency

in tibetan buddhism there is a saying: "our greatest enemy is our greatest teacher"
i have never considered anyone an enemy, i might be someone's enemy, but never intentionally, and i would never reciprocate. enemies do not exist in my belief system ... until saturday, february 27th. that day i came upon my enemy. my enemy was not a person, and in fact, my enemy took no sentient form at all. it was an extenuating set of circumstances: the circumstance of being unprepared for a dire medical emergency with our working dog: alone, without a vehicle or a phone, for days, just me, the internet, and my dog.
