person A: A close friend said she was having problems with her knee
person B: Ouch!  Did she hurt it or is it a degenerative thing? I hope she can find help with physical therapy.
person A: Hopefully she will see a doctor soon about it
person B: Oh good.  Hopefully she'll try to fix it with physical therapy first.  Some doctors love to do surgery right away when its not necessary.  Recommend that she get a second opinion.  Hope she resolves it!
