Would you tell your friend if they had bad breath?

No...not normally. People, today, are too fond of criticizing others. It can be very upsetting, even between friends. The only exception, I think, would be if we'd both agreed to always mention anything like that.

Yes, I would tell a friend they had bad breath. Not always easy, but I have done it. You can always refer to what they might have eaten last night, and suggest they have a mint or something. Personally I'd rather hear it from a friend than go around breathing on other people completely unaware of my very off-putting 'problem'.

They are your friend be honest with them and hopefully they will return the favour one day. I would want to know so I could do something about it.

If it was a one off i'd be inclined to offer a them chewing gum or a mint but if it was an on-going thing then i'd have to say something. I doubt I could hold my breath forever!

Yeah i agree with you there, friends should always talk to each other and have a good understanding of what is the best. Friends who help each other in the sorrow and happiness times are the real friends.
