No. Don't mention that you know. It'll get back to your w that you snooped. Don't act surprised either. You might want to just say something like, "I kinda figured this was coming. I'm glad she had you serve me instead of a stranger." You might ask if you could cut the evening short. She'll understand. I mean it would be ackward for you to say, "OK. Enough of that. Let's work on that resume of yours."
It will just be what it is paper, i won't act sad/mad/glad.. and will say something exactly like that " I kinda figured this was coming, glad it was you instead of a stranger" .. I'll just stay happy and positive (that is not what they expect i am sure)
after that it will likely be a wise decision to head to the gym..crank my ipod up and just run.. i will ask her if it's ok that i cut the afternoon short.
Hopefully she doesn't expect me to help her with her resume after that.. your right it would be ackward...
