<p>Thanks for the advice, everyone.</p>
<p>I checked my school’s housing handbook and she is allowed to have alcohol in the room. It just can’t be opened or consumed while I’m in the room. Also, they “consider age differences” when making roommate assignments, so I don’t think I’ll have much luck in asking the housing department for a different roommate. </p>
<p>Thanks again to those who offered advice.</p>
