How would you tell someone they have bad breath?

bad breath
CalexicoD asked:

My grandma wants to kiss me every time she sees me which is like twice a year. Not like a french kiss or anything, just a normal kiss. The problem is, she has HORRIBLE breath. Almost to the point of making me want to vomit.

My mom says I should just ignore it, it’s just the medicine but every time I go to the hospice she coughs up a lung through all these tubes before she asks me for a kiss.

I tried giving her a mint but the doctors told me she’s on a liquid diet for her final days.

i’m getting sick of dodging her and it almost makes her cry every time, but she smells so gross!

Is there a polite way to tell a woman she has bad breath or should I keep ignoring her?
