Xander loves his big sister

So, on our long drive back from California, Venice had a meltdown. Xander listened to the whole power struggle between Venice and me. At one point, I was ignoring Venice as she was making comments that did not deserve a response. She was chanting, "I'm stupid". As I was silent, Xander replied, "Don't say that." and, "Venice, stop saying that." Then, Venice said, "No one in the whole world loves me." After a few seconds of silence, Xander said, "I do." Is he the best brother or what?
