They are a complete nuisance, and I just think they get into Facebook and Skype through friends of friends, because both these on my computer are tuned in for friends and family only. One particular family member has family in America, and I think that is where the American calls keep coming from. She is constantly on Facebook telling everyone where she is and what she is doing. I am seriously considering cutting her off. I just share bowls information with bowls friends, and the occasional conversation with someone else on Skype.
