When they were younger, my kids bickered a lot. They’ve always gotten along fine, but there were times when they would argue about a lot of things. Now that they’re a little bit older, the fighting has decreased significantly. They are very close to one another. They hold hands while walking to their karate class. The older one accompanies his younger sister to her violin lessons. They both like watching “Dr. Who” and the “Star Wars” franchise. I hope they continue to be close to each other until they grow up.
