title: Actor in UML (Use case)
body: <p>Lets say i have Use Case A (Cancel Consultation),B (Destroy Patient Image) and Actor C (Patient).</p>
  
  <p>Use Case A includes Use Case B, and Actor C triggers Use Case A to happens. My question is, do i need to add a &lt;> from the Actor C to Use Case B ? I was thinking ,Use Case B happens only if Use Case A fires, which means Actor C ONLY triggers Use Case A. </p>
  
  <p>Not so sure that if Use Case A includes Use Case B, and Use Case A triggers by Actor C, therefore Use Case A and B has the primary actor of Actor C ???</p>
