People who don't pick up dog turds.
It's just taken me a year to get the council to clean a side alley by my house of dog turd, it was so bad it was piled and had been there so long it had moss over some of it.
After numerous complaints and telling everyone from Police, PCSO, streetcare and even telling them who did it. It finally got cleared last week.
I then caught the perpetrator in the back street with her dog and told her to make sure she cleans her poo up, in no uncertain terms.
Her reply was "I've just come out of an abusive relationship you know".
I don't get it.
