I suppose this is more of a wwyd than an aibu.
A very rowdy family just walked up my street, stopped in front of my drive whilst their DC (young teen, also laughing) threw up, laughed at my cat who thought it was dinnertime then continued walking up the street laughing.
I was down the side of the house and went out front, a bit shocked and watched them walk off at which point the mum turned around and shouted "What's she looking at? I don't have an effing mop n bucket. I didn't reply but washed the sick away.
So AIBU to think there's a better way to deal with this? What is the etiquette when throwing up outside someone's home? She had a point, she didn't have the means to clean up but it also feels wrong to just leave a puddle of puke. WWYD?
