history: I went to work a few weeks ago and found out that one of my coworkers that had quit many years ago was back. I was very shocked and happy to see them.  I was really excited to see that an ex coworker of mine moved back to town as was working with me once again.  Oh that is nice! Why did they move back?
current: Yea! They had moved away to take care of a sick relative, but the relative was doing much better and they missed being here so they came back.
next: Oh fantastic! I am sure they are happy to be home.
