Snow + wind +icy roads

Feel so guilty...I was running a lil late for class this morning, and finding parking at my sch is a HUGE pain in the tushies, while what happened was; I was going around the lot looking for a spot, and there was another car already doing the same. Lucky for me, there was a van leaving so I had my blinker on signaling that I saw that spot and the car that was waiting wanted that spot too. So what did I do? Well..I took the spot...ERGH...I can feel her cussing at me. I FEEL SO BAD after I took the spot. But what I can do? It IS a first come first serve thing right?
