Ever been in a situation where you can’t really tolerate someone or something but don’t know how to get your feelings across without making it sound mean/embarrassing.
I was at the barbers yesterday and it hit me. There is a way. A nice and subtle way. Depending on the nature of the problem, find an appropriate solution and gift it. e.g. Buy a perfume(stinking problem) or a gift card from one of the most expensive hair dressers in town(inappropriate hair-do problem).
Don’t make it obvious. Make it casual. e.g. I bought one for myself and thought you’d love it too.
