My cover letter to an incredible food analysis establishment that wouldn't even give me an unpaid internship after my interview.

They can block email, but they can't block snail mail. What will happen if I repeatedly send them letters and resumes in the mail, over and over? Eventually they gotta give me some recognition, even if it's "that weird kid who won't stop asking us for an internship". eventually they'll know my name as familiar. I will not stop until they give me a restraining order. I will not stop until I die. Even if I'm homeless on the streets, I will not hesitate to go camp in front of them.
