Young Love?

When the neighbor had her baby and I was pregnant and found out it was a boy we used to joke that Camden and Liva were going to be husband and wife. Lately when Camden hears the kids outside next door he wants to go out and play too. When he does he and Livi meet up at the hole in the fence and talk until one of them has to go in or we just go to each other's house. Could it be young love?
