Have you ever spent hours explaining a task to someone, only for them to go ahead and do exactly the opposite of what you asked them to do?
Or received a response to something you had said or written which indicated that the responder has clearly not taken in a word you said?
Or had someone tell you something as if it was new information, when you had told them the exact same thing some time earlier?
Or found out that something you thought had been agreed several weeks ago is actually still up in the air, because the other person didn't realise it had been agreed?
Or had someone repeat to you dozens of times that Option B is the best solution after you have made it clear that Option B is out of the question due to factors outside your control and you're trying to decide between Options A and C?
Or had someone demanding to know why you're aren't available at a time when you've already told them three times that you're going to be busy doing something else?
All of these things have happened to me this week, and I've found it quite frustrating.
Listening - it appears to be a dying art.
