<p>Thanks! (and sorry for such a... fosh question :))</p>
<p>Yes, they can. They’ll just hold it in the mail room until you pick it up.</p>
<p>random note - a lot of things stay open regardless of whether or not school is in session. For example, SHS is open year round except for school holidays (ie MLK jr day), and for a week around New Years.</p>
