Nettles have always been considered the bothersome weeds at home. My kids (dog included) learned to stay away from them after experiencing the pain that comes after touching them. You know how those little ones are. They only listen to you after experiencing the pain themselves. The dog's yelp and shrilly shrieks of Mommy seal the promise of never going close to them anymore.
The thing is, we have quite an abundant growth of nettles around the house that I keep on pulling and throwing away. They are delicious with risotto (which I have to share pretty soon too) but my cooking with them is limited there. When I was in the Republic of Georgia last spring, one of the best dishes I had was a very simple and fresh tasting plate of sautèed nettles.
