I am 32. I love my dad, he did his best. He was a good dad.
But I will probably never be able to forgive him for the times he shouted and yelled at me when I wasn't a good kid. He went into fits of rage over mundane things like homework and failing school. I remember everything he said in those fits of rage. Every instance of it. And I definitely remember feeling terrified.
And will remember it until the day I die.
Even at 70 years old.
Mostly on phones: On/Off settings that have vague names and no description at all. I don't know what is Multi Layered Scrolling is and I'm not going to research it. It stays off until it is explained right where the setting is.
Websites and apps: I HATE a confirmation menu that has a "OK" and "Cancel" type buttons where the one they want you to click is bigger, more emphasized, better colored and attractive than the other. This is common when you want to quit a game - the "Actually no I want to keep playing" button is usually highlighted and bigger while the quit button is ugly, in red, in the corner.
