so if you see someone yawn, you find yourself following. &amp;lt;i&amp;gt;just use that. &amp;lt;i&amp;gt;you yawn during class. &amp;lt;i&amp;gt;but if seung jo yawns after you, &amp;lt;i&amp;gt;then that means he has glanced over at you. &amp;lt;i&amp;gt;if he's not interested, why would he look at you?
