My grandma used to say: Who cares if it is half empty or half full? If there is something in it, you won't be thirsty.
I agree it's hard to unsee things. I usually avoid opening them if they look like they will be yucky. And today, opened a new topic because the old one was getting defensive. ( I admit, I was getting defensive, about something I thought mean.) So- switch gears and talk about the topic in a way not fraught with emotion and finger-pointing.
(It was about being mean to fat people, which got a bit heated. My topic is about food rules and how we can all eat better- the book and idea of eating better food as a society. Not so many emotional buttons.)
