<p>Is this a big no-no? Or is it okay if it was actually significant?</p>
<p>I would say it’s fine if it is truly significant to you. I actually wrote a supplement essay on an 8th grade experience.</p>
<p>It’s fine if it’s important to you. Just be careful not to include inside jokes or inside references, and be sure to explain the context of what’s going on.</p>
