Bromidrosis is the medical term use to described the condition of unpleasant body odours produce by excessive body sweating. Bad breath or halitosis is the number one smell that most people usually recognized. Those person experiencing this problem has also difficulty of realizing if they have bad breath or not. Frankly, I had bad experience about this. I never realized that I have bad breath in the morning until one of my crush or let's say the most person I liked gave me a mint gum to brush off the smell. I never felt so embarrassed in my whole life when he extended me those gum. Anyway, to make the story short. I was glad that he was so kind enough to just reached me the gum and never talked behind my back. At the instance he extended me the gum, there- I was so much aware that "I smell".
Sometimes, when you smell something you were confused of where the smell come from, either from the person behind your back, beside you, in front of you or maybe you. To find out the smell, you used the washroom or secluded places and smell yourself. Fortunately enough, you smell so good and you're confident that the smell is not yours.
The number one thing that you should remember is that you cared for your friend. You don't want her or him to get hurt by unpleasant feedbacks, so the best thing you can do is to tell the truth. Well, truth always hurts as a start but in the long run she or he will be grateful that you inform her or him. The truth will set her or him free. Free from unpleasant odours.
Don't be pretentious if you talk to her or him every time she or he open her or his mouth, you tried to hold your breath in order not to smell the air but too bad for you because you're struggling to catch your breath. Just tell her or him directly. If not, give her or him something to cure- this is not to offend her or him.
