Can this even be considered rude?

I'm sorry lady. I'm not sure if I should be sorry, but I am. I don't know if you are mad or frightened, I hope you thought it was funny. I was scraping the snow off my friends car and your car was just so snowy and close and ok ok ok I scraped two stripes. So technically I was helping. The look you gave me did not say thank you. I thought the lady walking down the street was an uninvolved party and wouldn't care who knew it was YOU the owner of the car. I was embarassed. I laughed. A lot. So I am sorry if you had plans for that snow or you are welcome for helping you gain better visibility. I didn't know the snow scraper ettiquite but I am sure you are fine. Good day.
