回答: @plebarae 私の兄はいつも祖母と話をしています。is a formal way when you talk to someone you meet at the first time etc. 兄はいつも祖母と話しています。is a bit formal when you talk to someone like your boss or coworkers at work. 兄はいつもおばあちゃんとばかり話してるんだよね。this sentence is casual and natural when you talk to your friends, your parents or your colleagues who are close to you almost like your friends.
