["My brother moved to California a few days ago. It was stressful for him, but he's always been good at thinking things through", 'I am sure the stress will be worth it in the end.  Just keep encouraging him!', "I will! I bet he will make lots of friends too. He's very outgoing and approachable"]
Those are good traits to have.  Good for him!
My brother moved to California a few days ago. I want him to do well there, and I want him to make lots of friends
