history: i am concerned about my father i am concerned about my father Oh no! What's wrong with your dad? he is old_comma_ and he lives alone.  i just worry because he is getting old.  he gets on ok_comma_ but i don't know how much longer.
current: Aw, I'm so sorry to hear that. It's not easy to watch our parents age. 
next: no it's not, but hopefully our kids will do the same for us some day.
