People who conveniently leave out and/or add words to what you said.
(note: this is not a scenario that inspired this post, it's just an example to help illustrate my point, thats it. There's nothing more to it)
Example:
Person A "I'll try to call you back at 7:00"
Calls back at 7:45
Angry Person B "you said you promise to call me back at 7:00!"
Thats a simple example but it happens all the time across all scenarios.
