WILL I FIGURE IT OUT?

Finally after a more than a week I got a call from my cousin apologizing for the cancelled family visit. She happened to call on Ralph and Kaitlyn's Birthday. What was funny about this call was she called me by accident. She was trying to get hold of someone else but dialed my number instead, lol. With her being so busy home schooling her two kids and running an online business I wonder which calling services she has. To my knowledge she has clients from Europe and other countries. And with her husband being computer savvy I am pretty confident she has the right calling services. I wonder how those things work. Is it the same as Skype? I haven't even figured out how to do conference call on our house phone. At least I finally figured out how to do conference call on my iPhone,lol.
