Answer:This misunderstanding is an example of: BYPASSING
Step-by-step explanation:
Bypassing it's a kind of misunderstanding in which we miss the point that was meant by the message passed to us; so a sender says something and we miss the point of what he wanted us to grasp in that message. This mostly because different words means diffrent things to different people so what one understands to means something else it may means something totally different to the other person. These differences in how we understand the context is the reason why the receiver will miss what was meant by the message sent.
