Seriously i need to know?

if it bothers you which it does. you should just turn your head while he or she is talking and say , excuse me excuse me but i feel that personal hygiene is a must when i go out in public because i respect myself and others now if you would like to speak with me please be sure to brush your teeth or turn your head while speaking to me if you cant figure out how to brush your teeth. Im not trying to be rude just trying not to gag or throw up while your talking to me . I want to thank you in advance for respecting my wishes in the future now proceed to talk but with you head turned.

Yeah most of them don't realize it

Because your s*hitty face attracts people with stinky breath

they don't know the difference

they may not realize the difference
