We are in the 6th week of school and I've had a lab partner whose breath is just FOUL. I think it may be a condition because this isn't morning-breath foul, this is sewage-material foul. He doesn't even have to open his mouth, the smell is like an aura around him. I've had classmates ask me how I deal with it, but I don't want to hurt his feelings. My lab is 2hrs 45 minutes and by the end I'm sick to my stomach literally.
Is there anything I should tell him? I dread going to lab now:(

You should speak to the teacher about it.
If the teacher refuses to do anything offer him an altoid ,if he says no just smile and say,*you kind of need one*.
Maybe he is unaware.
