 ===== Notes =====
-Put extra comments here (this section is optional)
+Mind the difference between the diagrams below: while "to do" process waits for the message all the time till the end, "no to do" process interrupts when the timer triggers. If the message arrives while we are clarifying delay with the client, it won't be caught and the process will hang after returning to the event gateway.
