history: My son just graduated from high school. He should have graduated last year, but didn't to what he needed to do to finish. I was so unhappy with him. My son should have graduated from high school in 2017_comma_ but he didn't. Why did he not graduate? He just didn't have the motivation to do what was needed. He did finally graduate this year though.
current: Did he go to college?
next: He just got his diploma in the mail a few days ago. He is not going to college. He is just going to find a job and work.
