How can you tell if you have bad breath?

bad breath
alexandria asked:

an i’m not talking about blowing in your hands and all that stuff.. i’m talking about how can you tell if people smell your bad breath?? Whats the body language like and what do they say to hint that you have bad breath?
i’ve had people offer me mints and one time someone offered me gum but i wasn’t close and they were also eating some themselves. i’m very confused… One time at my desk someone turned back and we started talking (she acted completely normal like she smelled nothing) and five minutes later after that she said randomly, “someones breath is kickin!”. Was that just to be funny? Or was that a hint?
No one ever avoids talking to me and I have alot of friends
