We re-started the Book of Mormon for our family scripture study this year, and a week or so ago we were reading about how the boys' mom started to murmur because she thought they were probably dead when they went to retrieve the brass plates from Laban. We talked about how long it must have taken to walk back to Jerusalem, and the first two attempts at getting the brass plates, etc. Then I explained that it was a long, long time ago, and there wouldn't have been any way for them to check in and let their mom know that they were OK. I said, "They didn't have any phones, or email or Facebook, or even a post office."
Dylan got big, wide eyes, raised his eyebrows and exclaimed, "Yeah, and they wouldn't have had any swim flippers, either!"
I wasn't sure how swim flippers were relevant to their situation, but I agreed. He was right, after all.
