Open House Etiquette

<p>So I know most adults bring checks to students at open houses, but if you are junior student going to a friend's open house do you need to bring anything?</p>

<p>Most of the ones I am going to I just met them this year so we're not super close but still friends, so I'm not really sure what the protocol is.</p>

<p>What do you mean "open house"? Like a graduation party?</p>
