Send Muire a proper professional email. Your introductory section should include any (school appropriate) information you would like me to know about you, what on-campus activities you participate in, and a book you enjoyed reading. Your middle section should address what, if anything, you might be considering as a career choice or field; if you don't have any idea, that's fine too, just tell me that instead. Your last section should include any questions you have about the course, the year, or me.
