Man posts letters into a dog poo disposal box for two years

This short-sighted 91-year-old man has been posting his letters into a dog poo disposal box for two years. Only when a passer-by tapped him on the shoulder and pointed at his mistake,  the man realised what he was doing wrong.

The man thought he was posting his letters into a Post Office box.

Admittedly, a dog poo box may look similar to a Post Office box in the eyes of an old short-sighted man.
