Oh no! What's wrong with your dad?
gpt
he is old, and he lives alone.  i just worry because he is getting old.  he gets on ok, but i don't know how much longer.

Aw, I'm so sorry to hear that. It's not easy to watch our parents age. 
gpt
no it's not, but hopefully our kids will do the same for us some day.
human
We can surely hope!
