Gnomes!

My son and my father were sculpting a few weeks ago at my father's house.  They were working on a gnome about 18 in high.  My wife bought a book to share with my father.

Upon close inspection of the apartment in Firenze, my son and my nephew became alarmed!

It appeared as though a possible gnome entrance had been sealed up.  My nephew spotted a small hole that was covered by a screen.  Maybe a gnome hack it open!

My son went outside to take a look.  He could not find the area that was sealed off.  He did find the place with a screen!  Should Nonno be worried about gnomes?
