What you say is going to be misunderstood.

There’s really not much to say, it’s just the nature of communication. You deliver a message from your own position, with your own understanding, and the other person interprets all of that from their own position, with a different understanding. This happens inevitably, no matter how close the speaker and the listener are. It’s not your fault. It’s not their fault. It’s just how it is.

The only thing you can do about it is to repeat the message over and over again.

Of course, you will become boring after while, people will start telling you they have already heard that, some will make fun of you, others will just stop listening and move on.

But it really is the only thing you can do about misunderstandings.

Just be careful that the message you choose to repeat is really the one that matters to your purpose.
