I hope you you had a successful week in Dortmund. Because of the bad weather at the last moment I could not get on my flight to Dusseldorf and I have stayed home. I was afraid to fly.
A ten year old kid should not be on Facebook. I would not be too concerned about your boys, because with facebook they can see who is approaching them, that means they can see the profile and social structure of their friends.
Thank you for your feedback, I have little knowledge of the German language, and at the moment I have to use the dictionary a lot, and I read many articles from online newspapers and magazines.
