It was hard for my boys when we made the decision to homeschool, they had spent their first three school years in traditional Christian school and had made friends (none of which they have kept in touch with). Then, we met a family so similar to ours it was amazing; 5 children and a homeschool family. The kids were all very close in age. We all were very excited, and the kids got along very well.
The kids have spent the past two days together, playing and making memories. Hubby and I have done our best to help out with both the moving and keeping the kids entertained. I still don't know how to answer their question. I do believe with the internet and all the technology of today, they can stay in touch. I know I'm going to do my best to let them try.
I know losing your best friend is not easy, and we will surely miss them. But, I have no doubt that God will bring someone into our lives here to help fill this void we are feeling. I also know that God will make their adjustments as smooth as possible since they are following God's will for their lives. I cannot be sad about that.
