You have a direct flight from Portland, OR to Portland, ME (5hrs) and are seated at the back of plane.  Just as the doors are about to close a person scrambles onto the plane and takes a seat right next to you across the aisle.  You immediately notice a pungent smell and can’t believe that a person could put on that much perfume.  The flight attendant notices that as others on the flight around you are starting to get annoyed by the smell you keep your cool.  The flight attendant taps you on the shoulder and asks why you are not as annoyed as the others.  You go on to tell her about how you recently learned about receptor desensitization and that in a few minutes the smell won't be nearly as pungent because your olfactory receptors will desensitize to the smell.  The flight attendant then asks you what desensitization means?  Provide your explanation below.  Be sure to include any general proteins that might be involved in this process.
