My friend is moving

Today i found out my friend Charlotte's husband has accepted a job in North Carolina. He starts mid-May. Charlotte and the girls will stay here thru August so she can finish up school. I told Ryan and Charlotte tonight. Ryan became tearful and said, "I won't see my friend ever again?" I reassured him we would see them all summer, "But then they'll be gone?" So he pondered this for a bit. Charlotte was worried about who was going to take her to Shelleys. I told her that she was going back to her preschool and she said Miss AJ knows how to get to the preschool so I had to call her and let her know. I told her Daddy or I would be taking her and Miss AJ would get her from time to time. Ryan wanted to know where NC was so we pointed it out on the map. He said' that's 10 hours away! We should fly there." I told them we could go visit and he wanted to know when. I told him that they needed to find a house and get settled and we needed to wait for an invitation. He thought about this and decided we needed to move there. I told him we can't move for 3 years. He did the math and figured out how old everyone will be. He wanted to know where in NC and I said I didn't know. He said "In 3 years we can move there" I said "To NC?", "Yes" he replied. "In the same town as Kristin and Kaylynn?" He smiled and said, "Yes, we can walk down the street, knock on the door, they'll open and there we will be!"
