What does a high level of eosinophils in a RBC/WBC differential suggest?

I'm a clinical laboratory science major and we did blood smears today and looked at them under a microscope of our own blood samples that we drew a few days ago during our venipuncture lab. My blood high a high number of eosinophils. I know this is the type of WBC found in response to allergens and things like that. My professor asked me if I had allergies. I said no. Then he said "I would ask another question, but I don't want to embar you". What would he have asked that correlates to a high eosinophil count that would have embared me?
