Communication can easily be misunderstood. It’s even easier to have a miscommunication with the written word as opposed to the in person spoken word.
When people are speaking with each other they can hear intonation, see body language, read gestures etc.
With the written word we only get the words. Because of this humor, sarcasm, connotations can all be misconstrued.
The thing to remember is when someone misunderstands what you wrote, it frequently is because of the readers preconceptions.
When someone misunderstands a written word, it’s not good enough to just correct the misunderstanding. You should also try to understand where it came from, why they interpreted things the way they did etc. When you do this, you will be able to vastly improve your communication.
Just something to think about.
Have a great day!
