But what does it mean?

I had a very strange dream last night:

I was living somewhere in Western Europe, working at some sort of musical instrument shop owned by Mrs. Atkinson, my high school ASL (yes, American Sign Language) teacher. Mrs. Atkinson had left earlier in the day for Germany with some sort of youth orchestra that she managed/conducted/whatever, so I'm running the shop alone. I'm supposed to drive to Germany after I close up to help her out with the orchestra thing.

Just as I'm about to close the store, this man and his daughter come in, wanting to buy a green oboe we have in the corner of the store. I think to myself that I should probably dust off the oboe and check it out before giving it to the daughter to try. As I pick up the oboe, I'm a little amazed that it's a) made of metal b) lacking a large number of levers I tend to associate with woodwinds c) got a mouthpiece like a flute. I have no idea how to play the oboe (in the dream, or in real life), so I blow into it, press some levers, and then hand it over to the daughter.

After a few minutes, the father comes to me and tells me that the oboe is playing a little flat. I look over at the daughter and the oboe; the reed she's using is made from cork and shaped like a styrofoam cup. "Well, yeah," I think. I can't get a hold of Mrs. Atkinson on the phone, so I tell the man to come back another day. Then I drive to Germany.
