Outside my DS's school (where he's been attending for the last 4 years), parents always park on the double yellow lines at drop Off and pickup times. I'm no different. Yet today or of the blue, one mum who arrived after me but managed to find a parking bay, started giving it to me loudly, saying I was breaking the law by parking on the double yellows and was responsible for knocking children off the road and killing them. I let her go on, and held my tongue simply as I didn't think it appropriate to create a scene right outside the school in front of kids etc. She was letting it rip, in front of her son. I kept my cool ...But I've come home, thinking about this incident, and really quite upset.
