I don't really know how to flesh out this paragraph. Like why would he even respond to some random letter that arrived in the mail? But he has to sign it to progress the story so that he can get the email. I dont know.

A few days later, a strange letter arrived. It asked me odd questions about my beliefs, fears, and values. It didn't bear a sender's name or address. Then, two days after that, an email notification pinged on my laptop from an unknown address. The subject line read: "Congratulations! You have been selected for Route 7734."
