One day Charlie hearing a knock on his door, open it to find Helmut - who lived across the street from him.

Helmut asked Charlie to stop picking his nose and explained his concern..

Charlie asked what business of Helmut's it was if he did pick his nose and how Helmut was even aware that he had been picking his nose in his home?

Helmut explained that everyday when he went up into his attic - stood on an orange box and looked out of his window into Charlie's house through his telescope - he could clearly see Charlie picking his nose.

Helmut explained that looking at Charlie picking his nose was not an activity that was to Helmut's taste - and insisted that Charlie must stop it.

Charlie pointed out that Helmut did not have to go up to his attic everyday, stand on an orange box and look out of his window into Charlie's house through his telescope and that if Helmut did not go to all this trouble - he would not even be aware that Charlie was indulging in an activity that was not to Helmut's taste.

Charlie perhaps did not use these words.

And Helmut carried on complaining.

But Helmut carried on standing on an orange box and looking out of his window into Charlie's house through his telescope.

And Charlie carried on picking his nose in his own home - when he judged it to be necessary and enjoyable.
