You Can't Understand

Just let me know, don't act like you understand my speech, when you cleary can't understand me.  Saying you can't understand me, would save me from interpreting your facial expression.  If you just admit you can't understand me, I wouldn't have to, unnecessarily, repeat myself.  Just act honest.  We have a very difficult time, in society, getting normal people to act honestly.  The pervasiveness of dishonesty, in the human race, pisses me off.
