Accidently rear ended partners car

Was on my way out of work yesterday, when my I was in my 07 Corolla and my foot accidentally slipped off the clutch and rear ended the partners Audi. It was at the gate that was at a somewhat steep incline in the parking garage as we were badging out. I am very embarrassed. Partner was cool with it, but it will be expensive.

My parents are pissed now that their rates are likely going to go up.
