Forget about it!

It's so frustrating when someone misunderstands one sentence you say, then proceeds to make a huge deal out of it while you're oblivious to anything going on. Even more so, it's annoying when someone else misunderstands a comment then tells someone else their own misunderstanding of it. That so pisses me off. The only thing you can do is forget about it until they ready to deal with it. That's life.
