I asked her sincerely if there was anything I could do for her and she said no.
I'm guessing she's just being polite. She doesn't have any family here and probably few close friends if any since they moved here just a year ago.
Is there anything I could do for her that you can think of? I know for now she and her husband are working. They go to the hospital after work, go home to eat dinner then go back later to say goodnight.
