I haven't called my dad for a long time, and I don't know what to say to him. What should I say?

You should say, "Dad, it's me. How have you been recently? How is the weather at home? " Wear less in hot weather, don't catch a cold, wear two clothes in cold weather, don't freeze. I'm busy recently, so I can't call you often. I hope you can forgive me. Actually, I miss you very much. I've had a little trouble recently. When this trouble is over, I will go home at once. That's it, dad. I hung up. "
