I would be very curious about any drugs they may have.
First off, if he asked me that I would ask him how he knows english. Or spanish, or french because I know those too. Then I would ask him how his spaceship works.
Then I would be best friends with him/her, take them out too eat. Show him/her to my friends and brag that I have an alien friend. Then ask him/her to destroy all the people I hate/dislike strongly.
After I have gained his/her trust, I don't think he would use me for medical examination anymore. Even if he still asked, I would confuse them to leave and not do anything to me.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
