College friend of mine is an attorney in France. About age 60 as am I. About a year ago she fell and broke her ankle. It was misdiagnosed/mistreated. Now she’s confined to a wheelchair and may never walk again. Having to work from home. The most they’ll give her for the pain is Tylenol. She’s having to smuggle Advil. After years of her telling me how much better things are in France - the food, the wine, the food, the wine, the food, the wine - I’m so biting my tongue every time I talk to her.
Why bite your tongue? You can make your point delicately and kindly but very firmly.
