When I get a new hair cut, for example, and its noticeable and no one says anything, its very sad/embarrassing. It means that its so bad that they can't even mention it. They think they are playing it up like they do not notice, but they do and I know and I get sad. I used to use that as my approach to not having to mention things, but I realized its rude because we all know I noticed and its just rude. It's even better to say its not THAT bad than to say nothing at all. But when someone says its not that bad, that means its pretty bad and that is sad. I also don't like when say for example when I did get that hair cut and someone stares at it for so long that they say they like it. No, you do not like it, you were just looking at its ugliness for so long you had to say something. In conclusion, when I get a bad hair cut:
a. if you do not say anything, I am sad
b. if you say its not that bad, I am sad
c. if you say you like it, I am sad
So, I now try to get less noticeable haircuts so I can just hope that they truly do not notice.
